This story has been updated to add a response from the Oregon Bureau of Labor and Industries.

Vancouver-based fast-food chain Burgerville will lay off 612 employees across its restaurant locations, the company announced Wednesday, a cutback that affects about 42 percent of the company’s total workforce of 1,482.

Burgerville restaurants have all been operating on a drive-thru or delivery-only service model since mid-March due to the COVID-19 pandemic and the associated statewide stay-at-home orders in both Oregon and Washington.

The company previously announced on March 23 that it would fully or partially furlough 68 percent of its workforce due to the change in operating conditions.

According to a spokesperson, the company later learned that Oregon’s Bureau of Labor and Industries considers a full furlough to be a layoff if it is expected to last more than 35 days, so all of the employees who had previously had all their hours furloughed would need to be laid off.
