The owner of three China Sea Restaurants in San Antonio has agreed to pay $504,577 to 82 employees after violating federal minimum wage, overtime and recording-keeping provisions, the U.S. Labor Department announced Wednesday.

“The employer used two books to keep track of wages, one for themselves and one for falsifying records. Their illegal actions hurt the workers’ families and our community,” Cynthia Watson, Labor Department regional administrator for the Wage and Hour Division in the Southwest, said in a prepared statement.

One set of records sent to a bookkeeper showed compliance with federal laws, the Labor Department said, but a second set revealed the employer was not paying minimum wage for all hours worked and the overtime was not paid.

“Kitchen staff at the three China Sea Restaurant locations routinely worked at least 60 hours per week, but their hours were not recorded. The employers paid kitchen staff a small salary that resulted in minimum wage and overtime violations. Additionally, servers were not paid properly and were owed overtime wages,” the Labor Department said.

The Labor Department filed the lawsuit on Dec. 21, 2012, in San Antonio’s U.S. District Court, initially seeking nearly $1.02 million in damages involving 164 restaurant workers. The investigation period was Dec. 22, 2009, to Dec. 22, 2012.

Sued were PCXAC LLC and WKHK Investment LLC, both owned by Peter Xac, which operates the three China Sea Restaurants.

Xac signed the consent judgment agreeing to pay back wages, damages and interest on April 7, Labor Department spokesman Juan Rodriguez said.
