Fitness-for-work decision

Procedure summary

Published On

Feb 3, 2026
Purpose

To determine if a worker is ready to return to work in their date-of-accident job or other suitable work and develop an appropriate return-to-work plan. 

Description

WCB Alberta is committed to helping injured workers achieve a successful recovery and a safe return to work at the earliest opportunity, including using appropriate modified work alternatives.

The decision maker monitors the worker's care plan including their progress in treatment and determines when a worker is ready to return to work based on medical reports.

When medical reporting supports a fitness level, the decision maker collaborates with the worker, employer and treatment provider to develop a return-to-work plan. Depending on the claim circumstance, a return-to-work plan could involve:

  • Return to full duties.
  • Return to modified duties or hours.
  • A graduated return to full duties or hours.
  • Return to suitable alternate employment.

The decision maker communicates the fitness-for-work decision verbally and in writing, explaining the medical information used to determine the worker's fitness level, work restrictions and the plan to support their return to work.  

Key information

Medical reports that assess a worker's capabilities are crucial for understanding the impact of an injury or illness on their ability to perform specific tasks. These reports typically evaluate the worker's functional ability to engage in activities such as sitting, standing, walking, lifting, bending, twisting, kneeling, squatting, climbing, overhead reaching, pushing/pulling, driving, etc. The findings help to determine suitable work accommodations or the necessity for rehabilitation services to support the worker's return to work safely and effectively.

The decision maker reviews the medical reports to determine the worker's work capabilities and work restrictions and compares the worker's fitness level with the physical requirements of their date-of-accident job including the frequency a task is performed. For psychological injuries, the decision maker considers other requirements for the date-of-accident job (e.g., social and cognitive requirements).

Before a fitness-for-work decision can be made, the physical requirements of the worker's date-of-accident job must be confirmed. When they are unclear, the decision maker obtains clarification by requesting a job description and physical demands analysis, or when appropriate, arranging a return-to-work planning meeting. It is best practice to obtain information about job requirements and modified work options early on in the claim. 

In some circumstances, the worker may not be capable of returning to their date-of-accident duties, but they may be fit for work with restrictions (i.e., modified duties). For example, if a worker's regular job duties require them to lift 11 kg (medium level) from their waist to an overhead position on a frequent basisA frequent basis is 34-66% or 2 hours 41 minutes to 5 hours 17 minutes of the workday., but they are only able to lift 11 kg on an occasional basisAn occasional basis is 6-33% or 25 minutes to 2 hours 40 minutes of the workday., this is considered a work restriction.

Modified work is one of the most effective ways to support the recovery of an injured worker and provides many benefits to both the worker and employer. When a worker is fit for modified work, the decision maker negotiates a return to modified duties with the worker and their employer. The plan is monitored until the worker is able to return to full duties or the work restrictions are confirmed to be permanent. Refer to the 3-1 Modified work procedure.

Both the worker and the employer have a duty to cooperate in the return-to-work process. For information about expectations of cooperation and participation in the return-to-work plan, refer to Policy 04-11, Part II, Application 1 - General.  

The worker's return-to-work plan depends on their fitness level, work restrictions and job availability.

There are four (4) possible fitness to work outcomes:

  • Fit to work without restrictions in their date-of-accident employment.
  • Fit to work with restrictions and modified work is available with the date-of-accident employer.
  • Fit to work with restrictions but modified work is not available with the date-of-accident employer.
  • Fit to work with restrictions and the worker's job with the date-of-accident employer is no longer available.

When a worker is cleared to return to their pre-accident job or modified work, the decision maker communicates the fit-to-work decision, discusses the return-to-work plan with the worker and the employer, and determines if the worker is eligible for wage replacement benefits and the type of benefit payable. 

Wage replacement benefits

A worker is eligible for temporary wage replacement benefits when there is medical evidence the work-related injury has resulted in temporary work restrictions which prevent the worker from resuming pre-accident employment or other suitable employment. The decision maker reviews the worker's fitness level and most appropriate wage replacement benefit payable.

Temporary total disability (TD01) benefits are payable while the worker is not fit for any work. These benefits are payable until the worker has a fitness level.  

Temporary partial disability (TD02) benefits are payable when the worker is fit for modified work, but they are earning less than their pre-accident salary. These benefits are payable until the worker is earning equal to or greater than their pre-accident earnings or the maximum compensable earnings for the date-of-accident year when the pre-accident earnings are higher. Refer to Policy 04-01, Part II, Addendum A - Maximum Annual Compensable Earnings.

Refer to Policy 04-02, Part II, Application 1 - General. 

In certain situations, when a worker possesses a fitness-for-work level but the date-of-accident employer is unable to offer appropriate modified work, the decision maker evaluates the worker's fitness level and readiness to engage in re-employment services.

A worker is not ready to begin re-employment services if they are in the acute phase of recovery (less than six weeks from the date-of-accident), they are participating in a return-to-work program or significant improvement is expected. Significant improvement means the worker is expected to advance to a higher work‑capacity level (e.g., from light duty to medium duty). If a worker can make minor gains (such as slightly better grip strength or range of motion) but is not expected to progress beyond the light‑duty level, they are considered job‑ready. In this case, RE services may begin to move the worker into the next phase of their return‑to‑work plan.

A worker is ready to participate in re-employment services when treatment is completed, the worker is still in treatment, but their fitness level is not expected to improve for 8 to 12 weeks, or the worker has reached the best level of function expected (a medical plateau) and no further improvement is expected. 

Re-employment (VR) benefits are payable when:

  • The worker has a fitness level but there is no modified work available with the date-of-accident employer and the worker's fitness level is not expected to change in the next 8 to 12 weeks. The decision maker refers the worker for re-employment services to focus on supports that could enhance their employability. This prepares them for a return to work, either with their date-of-accident employer or with a new employer if permanent work restrictions are identified and the date-of-accident employer cannot offer an alternate suitable job.
  • The worker has reached their best fitness level (medical plateau), has permanent work restrictions and the employer is unable to provide permanent accommodation through a suitable alternate job. At that point, a referral for re-employment services is made and re-employment (VR) benefits are payable. Refer to the 7-1 Triage assessment referral procedure.

Re-employment (VR01) interim benefits start when a fitness-for-work decision letter is sent, the worker is ready to participate in re-employment services, and a referral for a triage assessment is completed. These benefits switch to RE assistance (VR04) the day they begin SJS, and to retraining allowance (VR02) if the worker starts a full-time training program (i.e., full-time training is 30 hours per week or more). Refer to the 7-2 Supported job search or the 7-4 Retraining programs procedure. 

In some circumstances, a worker's injury results in a permanent disability that impacts their earning capacity. When the worker's condition stabilizes, WCB determines the impairment (loss) of earning capacity by assessing the impact the permanent compensable work restrictions will have on the worker's ability to earn in any suitable employment. Refer to Policy 04-04, Part II, Application 1 - Determining Impairment of Earning Capacity.  

Detailed business procedure

Expand all

Collapse all

1. Confirm fitness for work and prepare for the discussion.

Monitor and review incoming medical reports to confirm if the worker is medically cleared to return to work. Determine whether the medical information supports a return to their pre-accident job or indicates the need for modified work. 

Note: If a pre-existing condition is first accepted as temporary aggravation, but permanent work restrictions are later confirmed, reassess the decision to determine whether the temporary aggravation should be reclassified as a permanent aggravation. Refer to Policy 03-02, Application 1: Aggravation of a Pre-existing condition.

To determine if the worker is fit for full or modified duties, review the worker's capabilities and restrictions indicated in the medical report and compare them to the requirements of their pre-accident job (e.g., job description, physical demands analysis, and social and cognitive demands when applicable). If this information is unavailable, obtain clarification of the job requirements. Refer to the Classification of work capabilities section below.

Identify other relevant details to support a return-to-work plan. Consider:

  • When the work restrictions are likely to resolve and any recommended treatment to help the worker fully recover.
  • Previous modified work discussions, if the worker is capable of returning to lighter duties.
  • Whether return-to-work barriers were previously identified (e.g., transportation issues, limited or no modified work available based on prior discussions).

If the medical reporting is unclear on the worker's fitness for work, request clarification by contacting the treatment provider and send the appropriate letter. 

If required, send a referral to the medical consultant for an opinion on the worker's work capabilities and restrictions. Review the medical consultant's opinion and action recommendations, as appropriate. If the worker's fitness for work is still unclear, consider what additional information or further medical evaluation is needed to determine fitness for work and/or work restrictions (e.g., a return-to-work planning meeting, comprehensive functional capacity evaluation, independent medical exam).

Note: If the worker is under the care of a surgeon, clearance is required prior to referring for medical assessments such as a functional capacity evaluation.

If there is a conflict of medical opinion about the worker's fitness for work, follow the 1-9 Conflict of medical / psychological opinion procedure. Once addressed, return to this procedure to make a fitness-for-work decision.

Assess the worker's job readiness and prepare for the discussion

If the medical reporting supports the worker has a fitness level, assess the worker's job readinessA worker is job ready when they are non-job attached or all attempts to negotiate modified work are exhausted, they are fit for some level of work, and they are not expected to have a significant increase in their functional abilities over the next 8 to 12 weeks. A fitness decision can be made. by reviewing the treatment plan to confirm if changes in the worker's fitness level are expected within the next 8 to 12 weeks.

Prepare to discuss:

  • The fitness-for-work decision with the worker and the employer including work restrictions, if applicable.
  • Modified work opportunities when there are temporary or permanent work restrictions. Refer to the 3-1 Modified work procedure.
  • The worker's fitness level, whether they are job-readyA worker is job ready when they are non-job attached or all attempts to negotiate modified work are exhausted, they are fit for some level of work, and they are not expected to have a significant increase in their functional abilities over the next 8 to 12 weeks. A fitness decision can be made. and the type of benefit payable.

When the medical information supports the worker is fit for their full duties, the worker is job-ready. Prepare to explain that temporary total disability (TD01) benefits will end because they are capable of returning to their accident job. 

When medical information supports that the worker is fit for modified work and:

  • modified work is available with the date-of-accident employer, prepare to explain that while working modified duties temporary partial disability (TD02) benefits may be payable if the worker earns less than their pre-accident earnings or the maximum compensable earnings for accident year when the pre-accident earnings are higher. These benefits are payable until the worker is earning equal to or greater than that level (either the pre-accident earnings or maximum compensable earnings). Refer to Policy 04-01, Part II, Addendum A - Maximum Annual Compensable Earnings.
  • modified work is not available, and significant improvement Significant improvement” means the worker is expected to advance to a higher work‑capacity level (e.g., from light duty to medium duty). If a worker can make minor gains (such as slightly better grip strength or range of motion) but is not expected to progress beyond the light‑duty level, they are considered job‑ready. In this case, RE services may begin to move the worker into the next phase of their return‑to‑work plan. in the worker's fitness level is:
    • expected within 8 to 12 weeks, the worker is not job-ready. A fitness for work decision should not be made. Continue to pay wage replacement (TD01) benefits and keep negotiating modified work with the date-of-accident employer as the worker progresses in their recovery and their fitness level improves. Prepare to discuss a referral for an RE triage assessment to see if the worker would benefit from skilling up or an ergonomic assessment. Ask the employer if skilling up services would open up more modified work opportunities.
    • Is not expected to improve within the next 8 to 12 weeks, the worker is job-ready. Prepare to discuss long-term modified work or permanent accommodation. If these options are not available within three months, explain the need for an RE triage assessment referral. Clarify that RE services may involve supports to improve the worker's employability, such as skilling-up services or retraining. Advise that wage replacement benefits will change to RE (VR01) benefits. 

Administrative tasks

 

 

Follow the 1-6 Aggravation of a pre-existing condition decision procedure.

Update the eCO Injury Details screen, if required.

 

If not already on file, ask the employer to provide a copy of the worker's job description and complete the physical demands analysis form, either:

  • the Employer's Physical Demands Analysis (C545) form or
  • the Cognitive-Psychosocial Job Demand analysis (C1447) form

 

 

 

To request clarification from the treatment provider, send the Request Medical on Modified Work VR Non-VSCVisiting specialist clinic (SP063A) letter or the appropriate SP006 series letter. 

 

If clarification regarding fitness for work is required from a VSC surgeon, follow the 4-1 Medical testing, referrals and program support procedure.

To send a referral to the medical consultant, follow the 11-2 internal consultant referrals procedure.

2. Call the employer to discuss fitness for work and benefits

Call the employer to discuss the medical evidence supporting the worker's fitness for work, any applicable work restrictions and whether those restrictions are expected to be temporary or permanent. If temporary, confirm the expected duration and what steps will be taken to verify when the restrictions end.

Explain if wage replacement benefits will end or change and if a referral for re-employment (RE) services is appropriate based on the claim circumstance outlined below. Refer to Policy 04-02, Part II, Application 1 - General.

Fit to return to the pre-accident job

Explain that wage replacement benefits will end because the worker is cleared to return to full duties. Wage replacement (TD01 or TD02) benefits are paid up to and including the date the decision is first communicated. 

Fit with work restrictions, modified work available

Ensure that the available modified duties are within the worker's restrictions and confirm the date the worker will return to them. Refer to the 3-1 Modified work procedure. Explain whether partial wage replacement (TD02) benefits are payable. Discuss the modified return-to-work plan including monitoring details and when the worker is expected to return to full duties, if appropriate. 

Fit with work restrictions, modified work not available

Assess the claim to determine if a referral for RE services is appropriate. 

Ask the employer if:

  • The worker would benefit from skilling up services to support a modified work opportunity. Skilling up is appropriate when it is purposeful and will enhance the worker's return to work with their employer.
  • They expect to have modified work for the worker within the next three months.
  • Permanent accommodation Permanent accommodation refers to lasting changes to a worker’s duties, schedule, environment, or equipment required due to a work‑related injury. These adjustments ensure the worker can safely perform a position that is suitable to their permanent work restrictions. for their worker is available when permanent work restrictions are expected.

If the employer is:

  • Able to provide modified work or accommodate the worker's permanent work restrictions within the next three months, confirm the details of the position (if available) to ensure it is suitable. Refer to the 3-1 Modified work procedure.
  • Unable to provide modified work within the next three months or they cannot accommodate the worker's permanent work restrictions, explain that a referral for an RE triage assessment will be made, the reason for the referral (e.g., help the worker find suitable alternate work or identify modified work opportunities), and that the worker will switch to re-employment assistance benefits (VR01).
3. Call the worker to discuss fitness for work and benefits

Call the worker to discuss the medical evidence supporting their fitness for work, any applicable work restrictions and whether those restrictions are expected to be temporary or permanent. If temporary, confirm the expected duration and what steps will be taken to verify when the restrictions end.

Explain if wage replacement benefits will end or change and if a referral for re-employment (RE) services is appropriate based on the claim circumstance outlined below.

A fitness-for-work decision and its rationale may be communicated verbally before the medical report is received. However, the report must be on file before sending the fitness decision letter. 

Fit to return to pre-accident job

Explain that their wage replacement benefits will end because they are cleared to return to full duties. Wage replacement (TD01 or TD02) benefits are typically paid up to and including the date the decision is first communicated. 

Fit with work restrictions

Discuss the details and outcome of the conversation with the worker.  

When the employer is able to provide modified work or accommodate the worker's restrictions within the next three months, discuss the details of the available position, including the estimated start date (if known), how the duties meet the worker’s restrictions, and the plan for follow‑up or monitoring. Explain any changes to wage‑replacement benefits (e.g., TD02 or the benefit type payable while the worker is waiting for modified work to begin when the start date is delayed). Refer to step 1. 

When the employer is unable to provide accommodation within the next three months or they cannot permanently accommodate the worker's permanent work restrictions, determine if the worker is ready to participate in RE services. Refer to step 1. 

If the worker is job-ready, confirm their agreement to attend the RE triage assessment. Collaborate with the worker to resolve barriers that may impact their participation (e.g., travel arrangements, childcare, interpretation services).   

If the worker decides not to cooperateCooperation means full participation and disclosure, as required, in those activities and services at each stage of a claim that are focused on supporting a worker’s recovery and return to work. in RE services, and they are:  

  • not job-readyA worker is job ready when they are non-job attached or all attempts to negotiate modified work are exhausted, they are fit for some level of work, and they are not expected to have a significant increase in their functional abilities over the next eight weeks. A fitness decision can be made., but long-term or permanent work restrictions are anticipated, work to resolve their concerns. If they still do not agree to participate, attempt to obtain their agreement to participate in RE services, once they are job-ready. Benefits are not impacted (e.g., not reduced or suspended) because the worker is not yet job-ready.
  • job-ready, discuss the reasons they are not able to attend, their duty to cooperate and any impact to their wage loss benefits. When a worker cannot or will not participate in RE services, explain that services will be completed on a documentary basis and discuss the reason why this is appropriate and the expected outcome of the service. Consider a referral for a job option report to identify a suitable job option to use to estimate earnings (i.e., to determine what benefits may be payable to the worker for the period they are unable to participate.
  • When benefits are reduced or suspended because a worker did not meet their duty to cooperate, consider reinstating them when the worker starts to participate in RE services.

Skip to step 4 to communicate the decision in writing unless the worker or employer disagrees with fitness-for-work decision or identifies barriers, then continue to the next step.

Administrative tasks

Document the discussion in a file note (Modified Work/Claimant Contact or Employer Contact).

 

Update the eCO Return to Work and Work Restrictions screens.

 

 

 

 

 

 

Follow the appropriate procedure:

  • 3-1 Modified Work
  • 3-3 Duty to cooperate
  • 7-1 Triage assessment referral

 

 

 

4. Address barriers and identify solutions

Identify any barriers that prevent the worker from returning to work (e.g., transportation or childcare issues) and discuss solutions to resolve the barrier. For example, if transportation is a concern, consider how the worker got to work prior to the injury. Is carpooling or public transportation is an option?

When the worker or employer disagrees with the fitness-for-work decision, work together to resolve their concerns. Consider what assistance is available to resolve the disagreement and/or clarify the worker's work capabilities. Work together to develop a plan to obtain consensus about returning to work or to resolve the issue. 

Consider the following available supports to address the issue:

  • Telephone contact with the treatment provider to clarify the worker's fitness level, work restrictions or whether modified duties are suitable. 
  • A referral to an internal consultant to review the available medical reports or to call the treatment provider to gain consensus on the worker's fitness level.
  • A referral for a return-to-work planning meeting to confirm the physical demands of the date-of-accident job and identify opportunities for modified work or for assistance in developing a gradual return-to-work plan.
  • A referral for a comprehensive functional capacity evaluation to confirm work restrictions (i.e., pushing/pulling and lifting capabilities, ladder climbing, etc.)
  • An independent medical exam to confirm work restrictions.
  • Referral for a psychological assessment or cognitive assessment for psychological injuries or brain injuries. 

Call the worker and the employer to discuss the outcome of the referral including clarification of the worker's fitness for work and work restrictions and if wage replacement benefits will end or change. Refer to step 2. 

Administrative tasks

Follow the appropriate procedure:

  • 3-1 Modified work
  • 4-1 Medical testing, referrals and program support
  • 5-5 Child and animal care
  • 11-2 Internal consultant referrals

 

 

Update the eCO Return to Work and Work Restrictions screens with any changes, as appropriate.

 

 

 

 

Document the discussion in a file note (Modified Work/Claimant Contact or Employer Contact).

5. Communicate the decision and make referrals, if appropriate

Send the appropriate letter to communicate the fitness-for-work decision in writing. Include the following information in the letter:

  • The medical information used to make the decision including the report date and treatment provider's name. The decision, and rationale for the decision, can be communicated verbally and before the medical reporting comes to file. The decision is formalized in writing once the medical report is on file and the decision maker confirms the facts on that report.
  • Specific work restrictions.
  • Details of modified duties performed or offered.
  • The gradual return to work plan, if applicable.
  • Details about benefits changing or ending. Refer to Policy 04-02, Part II, Application 1 - General.
  • The goal date for return to full duties if the worker is returning to modified work.  
  • Any update to the care plan including continued treatment plan or additional medical assessments.
  • Any referrals required such as for re-employment services.

Note: In most circumstances, the medical information referenced in the discussion with the worker is already on the claim file. If the medical report referenced in the decision discussion comes to the file after the conversation, review the information when the report is received to confirm the decision is correct and aligns with the information communicated. Then send the appropriate decision letter to formally communicate the fit for work decision.  

When the worker is fit with restrictions or requires permanent accommodation, continue to negotiate modified work if a return-to-work date has not been confirmed.  

Send a referral for re-employment services, if required, and as discussed with the worker and employer.

Administrative tasks

  • Fit for work - Date-of-Accident (CL041C)
  • Fit for Work - Modified (CL041X)
  • Fit for Work - Restrictions and WLS Pending (CL041Z)
  • Fit for Work - Care Plan - Combined (CL041I) 

 

Follow the appropriate procedure:

  • 3-1 Modified Work
  • 3-3 Duty to cooperate
  • 7-1 Triage assessment referral

Supporting Information

Classification of work capabilities

 Work capabilities may include a fitness for:

  • Sedentary/Limited work - Exerting up to 5 kg (11 lbs.) of force. Example: An occupation where the worker sits most of the time, and only walks or stands for brief periods.
  • Light work - Exerting up to 10 kg (22 lbs.) of force. Example: Walking or standing to a significant degree or sitting constantly but with arm and/or leg controls with exertion of force greater than limited. 
  • Medium work - Exerting up to 20 kg (44 lbs.) of force. 
  • Heavy work - Exerting over 20 kg (44 lbs.) of force. 

When determining a worker's fitness for work and suitability for a position, the decision maker also considers the frequency at which the task is performed. For example, if a worker is capable of lifting at a light level overhead but should limit the frequency over the course of a workday, this would be noted as a work restriction. Frequency capabilities are reported as follows:

  • Not required - 0% or 0 hours of the workday
  • Rare basis - 1-5% or 1-24 minutes of the workday
  • Occasional basis - 6-33% or 25 minutes to 2 hours 40 minutes of the workday
  • Frequent basis - 34-66% or 2 hours 41 minutes to 5 hours 17 minutes of the workday
  • Constant basis - 67-100% or 5 hours 18 minutes to 8 hours or greater of the workday

This reference chart includes examples of jobs or duties that fall within each classification of work.
