A Federal Way business is shuttering, resulting in 164 workers who will be laid-off starting Dec. 31.

QualChoice Health Plan Services is going to close its door permanently at the end of the year for currently unknown reasons.

Local rapid response teams and WorkSource Center will be helping with employee outreach to make the transition easier for the affected employees.

A Worker Adjustment and Retraining Notification (WARN) announcement was sent out Nov. 1 after the company notified them of the closure.

According to their website, the WARN act requires companies with more than 100 employees to notify affected workers 60 days before any closures or layoffs.

QualChoice was unable to return comment before press time.
