A National Labor Relations Board judge ruled Wednesday that Whole Foods did not violate the law by forbidding workers from wearing Black Lives Matter clothing and accessories on the job.

Administrative Law Judge Ariel Sotolongo wrote in his decision that the grocer maintained an illegally broad prohibition against employees donning messages on their work clothes. But he decided that Black Lives Matter messaging itself was not protected activity under the law because it wasnt related directly to workers jobs.

The case stemmed from several walkouts and protests at Whole Foods stores around the country where workers were instructed to remove Black Lives Matter pins and clothings.

The workers and the labor boards general counsel argued that banning the racial justice messages violated their protected right to band together and advocate for a better workplace. Sotolongo disagreed.

While acknowledging the case was novel and complex, Sotolongo wrote that there was simply no evidence that there were employee concerns about racial inequality on the job before they started wearing Black Lives Matter messages on their clothes.
