When an injured worker in Pennsylvania is able to perform light or modified duty work before fully recovering, workers comp benefits shift from temporary total disability (TTD) to temporary partial disability (TPD) — also called a wage differential benefit. The wage differential is the difference between your pre-injury average weekly wage and your current reduced earnings, paid at 67% under most state formulas. For example, if you earned $1,000 per week before your injury and now earn $600 per week in light duty, your wage differential would be 67% of $400, or approximately $267 per week from workers comp.
Employers in Pennsylvania have a financial incentive to offer light duty work because it reduces their workers comp costs. You have the right to refuse light duty if the offered position exceeds your physician's medical restrictions. If your employer's light duty offer is within your restrictions and you refuse without good cause, your TTD benefits may be suspended or reduced. Always obtain written documentation of the specific duties, physical demands, and hours of any light duty position before accepting — and have your treating physician confirm the position is within your restrictions in writing.
Once you return to full duty, your TTD and wage differential benefits stop. However, if you subsequently need additional medical treatment, the claim remains open. The Pennsylvania Bureau of Workers' Compensation oversees return-to-work disputes in Pennsylvania, and you have 20 days to challenge a decision you disagree with. Keep detailed records of all offers of modified work and all correspondence with your employer and their insurer during the return-to-work process.

A wage differential benefit in Pennsylvania pays the difference between your pre-injury average weekly wage and your reduced post-injury earnings, multiplied by the state's benefit rate of 67%. It kicks in when your doctor clears you for light or modified duty work but your new reduced wage is lower than what you earned before the injury. It bridges the income gap while you continue to recover.
In Pennsylvania, you can refuse light duty if the job offer genuinely exceeds your physician's work restrictions. If the offered duties are within your restrictions and you refuse, your TTD benefits can be suspended. To protect yourself: (1) get the job description in writing, (2) have your doctor review it and confirm whether it's within restrictions, and (3) respond formally in writing if you believe the offer exceeds your restrictions.
Wage differential / TPD benefits in Pennsylvania typically last up to 500 weeks from the date of injury, or until you return to your pre-injury wage, reach MMI, or reach the state's maximum benefit period. In some states, TPD benefits have a separate, shorter duration cap than TTD. Contact the Pennsylvania Bureau of Workers' Compensation or an attorney if your employer terminates your wage differential benefits before you have fully recovered.
