Light Duty and Work Restrictions in California Workers’ Comp

How light duty actually works in a California comp claim: what makes a modified-work offer valid under §4658.1, what happens to TD when you accept or refuse, earning less on restricted duty, the voucher connection, and the traps on both sides of the offer.

The restriction slip — “no lifting over 20 pounds, no overhead work” — turns every comp claim into a three-way negotiation among what the doctor wrote, what the employer can offer, and what the checks require. The rules are more mechanical than either side admits.

What makes an offer valid

“Light duty” has legal elements (§4658.1): the assignment must fit the written restrictions, sit within reasonable commuting distance, be expected to last at least twelve months, and pay at least 85% of the wages at injury. An offer that meets them and gets refused generally stops TD — the wage loss stops being the injury’s. An “offer” that fails them (a two-week token assignment, a facility across the county, duties that quietly exceed the restrictions) is not the offer that cuts anything off.

Working it: the differential

Accept and earn less — fewer hours, lower classification — and TD converts to partial: payment rides the wage differential, not the full loss. Working light duty also builds the record both directions: it evidences good faith and earning capacity, and it tests the restrictions in public. Which is the trap — exceeding your restrictions at work (or on camera in the parking lot) is the defense exhibit that shrinks cases. Work the restrictions as written; get them changed by the doctor if they’re wrong, not by improvising.

The 60-day voucher window

Light duty’s endgame arrives at P&S: a qualifying regular/modified/alternative work offer within 60 days forecloses the supplemental job displacement voucher (§4658.7); silence or a non-qualifying offer triggers it — and SB 863 made it non-settleable. Either way the PD rating is untouched: permanent disability compensates the injury, not the job outcome — the string prices the same whether you are back at work or not. Employers running this from the other side: the employer’s guide.

FAQ

Do I have to accept light duty from my employer?
If the offer genuinely fits your doctor’s restrictions, refusing it generally stops temporary disability — the wage loss is no longer the injury’s fault. The leverage is in the details: a valid modified/alternative-work offer must fit the restrictions, sit within reasonable commuting distance, last at least twelve months, and pay at least 85% of your wages (§4658.1). An offer that fails those elements is not the offer that cuts off TD.
What if light duty pays less than my regular job?
Working reduced hours or a lower-paid assignment converts total TD into partial: the system pays on the wage differential rather than the full wage loss. You are not choosing between working and benefits — the combination is designed to keep income near the TD level while you recover.
What if my employer has no light duty available?
Then TD continues while you remain restricted — the employer’s inability to accommodate is not the worker’s wage loss to absorb. And if no qualifying offer arrives within 60 days of permanent and stationary, the supplemental job displacement voucher comes into play (§4658.7).
