An assisted living facility in Daly City was ordered to pay more than $639,000 to 48 workers who were not paid minimum wage for all hours worked, following an investigation opened because of a complaint over lack of workers’ compensation coverage.

“The Labor Commissioner’s Office opened an investigation at Amore Retirement Living last June after receiving a complaint that the employer did not have workers’ compensation insurance,” the Department of Industrial Relations said in a statement. “Investigators found that the 53-bed facility lacked coverage for the previous five years and uncovered many other labor law violations.”

Workers were required to be available around the clock, but they were not paid for all hours they worked, the DIR said.

Kysella Trismeo Corp, the care home’s licensee, was cited $469,103 in June 2018 for not carrying workers’ compensation coverage.
