New Benefit for Retro Members: Return to Work = 100% Wage Reimbursement

WSDA has a great new benefit for Retro participants! Bringing injured employees back to modified duty as soon as possible – also known as Return to Work (RTW) – just got more beneficial. Currently companies can get reimbursements from L&I for up to 50% of wages. Now, WSDA will match the 50%, so participants can get up to 100% of wages reimbursed.

The success of the WSDA Retro program requires members to control claim costs. We are helping practitioners do just that by implementing this new program that pays for providing modified duty work to employees who are not able to come back to their job of injury.

Why Sign Up?

  • Become qualified to receive refunds on workers’ compensation premiums you already pay to L&I.
  • Get up to 100% of wages reimbursed when bringing injured employees back to modified duty.
  • Receive assistance with workplace injuries from ERNwest professionals, who will work directly with L&I on your behalf to quickly and reliably manage claims.
  • Implement effective strategies to keep your premium rates down.
  • Access easy-to-read reports outlining claim activity and costs, along with ERNwest representatives available by phone.

Support from Workers' Compensation Experts

WSDA Retro is more than a potential refund — it is also support from workers’ compensation experts who are available to all WSDA Retro-enrolled members if they ever have an L&I claim. WSDA has partnered with Employer Resources Northwest (ERNwest) to manage our group.

ERNwest is a Washington company that for the last 20 years has helped Retro members understand the program and implement best practices so they are poised to get great refunds.
