Employees staffed by Simos Insourcing Solutions filed suit in the Will County Circuit Court today alleging that they were denied benefits promised to them when they were originally hired to work at the Walmart warehouse located in Elwood, Illinois. This is the second time a suit has been filed by workers at this particular warehouse in as many months.

“Simos promised me that I would earn vacation pay while I worked there, but apparently that was an empty promise,” said Willie Jones, one of the lead plaintiffs, in a press release announcing the suit. The class action lawsuit also alleges that the temporary staffing agency forced the workers to incur fees in order to receive their paychecks and says they were not given specific employment information, including the terms of their pay and benefits, as mandated by Illinois law.

This is the second lawsuit to come out of the Elwood Walmart warehouse this year. In March, temp workers from Reliable Staffing Group filed suit saying they went unpaid for their work and toiled in unsavory working conditions, amongst other allegations of employment law violations.

Here's what Robert Hines, a former employee of a factory serving Walmart who is involved in a separate lawsuit concerning the retailer, has to say to those considering a job at a Walmart store or warehouse as the corporation continues its push to expand in Chicago:

Hines took part in a "truth tour" of Walmart warehouse workers who detailed their experiences working on various stops on the retailers supply chain in March.
