Two Utah firms and their owners have been sued in federal court, accused of violating the Federal Labor Standards Act.

The separate lawsuits against Anderson's Roofing and Repair Corp. Orem, and J&C Enterprises Inc., Vernal, say both companies repeatedly required employees to work longer than 40-hour work weeks.The government is seeking unpaid overtime compensation from Anderson Roofing and owner M. Dean Anderson of $24,320 for 23 employees for a period from May 1988 to September 1989, as well as a judgment for additional overtime worked since 1989.

The suit against J&C Enterprises and owner Charles Lewis seeks $17,953 in overtime compensation for 13 employees for a period from May 8, 1988, to Dec. 31, 1989, plus an additional judgment for overtime worked since then.

Both companies violated federal law by failing to make, keep and preserve detailed employee records, the lawsuit says. The plaintiff in both cases is Roderick A. De Arment, acting U.S. Secretary of Labor.
