IKEA can’t escape part of a would-be class suit claiming the furniture giant skimped on employee wages, a federal court ruled June 11.

Terri Powell was a pack team captain for IKEA from 2014 to 2018. She claims the company has a policy of “rounding” its employees’ clock-in and clock-out times to its own benefit. If she worked from 6:20 a.m. to 3:07 p.m., for example, the company only paid her from 6:30 a.m. to 3 p.m, she says. In one two-week pay period, that rounding cost her 118 minutes worth of wages, she claims.
