About 10,000 workers are joining a suit against Chipotle, saying they were forced to work unpaid off the clock, according to CNNMoney (hat tip to Mashable). The suit originated in Colorado and quotes one employee as saying workers were routinely told to clock out and keep working before being told they could leave.

Chipotle told CNNMoney that it has done nothing wrong and has paid what it owes to workers.

The restaurant, which serves made-to-order fare in a fast-casual setting, has faced legal encounters before. On the labor front, a March 14 ruling by an National Labor Relations Board administrative law judge in Philadelphia slammed the company for social media policies and employee handbooks that violated the National Labor Relations Act. A class action lawsuit against Chipotle Mexican Grill over genetically modified ingredients survived a motion to dismiss in Miami federal court earlier this year.
