SALEM, Ore. (AP) — Cover Oregon has offered retention bonuses to employees who stick around through a tumultuous time for the struggling health insurance exchange.

Cover Oregon officials say the bonuses are necessary to avoid losing needed staff members. They could cost up to $650,000.

The organization has been struggling with the loss staff in recent months, some to layoffs and others who left voluntarily.

Most employees can earn two weeks of pay if they stay through March 15. About three dozen employees deemed essential can earn more, with two people eligible for bonuses worth three months of pay.
