The National Labor Relations Board issued a complaint alleging that four companies involved in staffing a Walmart distribution center retaliated against workers who organized and participated in a strike.

A complaint issued by the National Labor Relations Board alleges that four companies involved in staffing a Walmart distribution center retaliated against workers who organized and participated in a strike, according to The Nation.com.

Josh Eidelson reported on Wednesday that the NLRB alleged in a Feb. 28th complaint that the companies threatened workers who were involved in organizing activities and in some cases went as far as to fire them. Employees at the Elwood, Ill., warehouse went on strike for three weeks in September and caused it to shut down temporarily.

As Eidelson writes, there are currently dozens of charges related to Walmart before the board, placing pressure and increasing scrutiny on the company as efforts to organize low-wage workers continue to gain traction.

MSNBC host Chris Hayes discussed how companies like Walmart respond to complaints about labor conditions and spoke with workers who were involved in organizing the Black Friday strike on the Nov. 18th episode of Up with Chris Hayes.
