Nearly 10,000 workers are suing Chipotle for wage theft

Almost 10,000 workers have a complaint against Chipotle.

The workers are suing the burrito chain for wage theft, claiming they were forced to work off the clock with no pay.

The case was filed in 2014, but 9,961 current and former employees had signed on to the class-action lawsuit as of Friday, CNNMoney reported.

The suit, Turner v. Chipotle, is the largest class action Chipotle has faced. It's being adjudicated in Colorado.

In April, all hourly employees who worked at Chipotle after February 2012 were mailed a card asking if they wanted to sign on to the suit. Employees in every state with Chipotle locations have signed on, CNNMoney reported.

The workers allege they often had to continue closing down and cleaning up stores after they were automatically clocked out at 12:30 a.m.

The case is gaining steam after a rough year for Chipotle. The chain is still recovering from the E. coli epidemic that rocked its restaurants across the country, and then its stock prices.

In its most recent earnings call, the company said it was still struggling to bounce back from the outbreak's effect on business. Its sales dropped 16.6 percent, to $998.4 million, in the second quarter of 2016 compared to the same period last year.

Chipotle also lost in front of the National Labor Relations Board last week when the organization ruled that the company's social media policy violated federal labor law.
