Unionizing efforts have begun for Apple store workers, according to an article in the Washington Post on Friday.

The outlet reports that two Apple retail stores are being backed by national unions and are planning to file paperwork with the National Labor Relations Board (NLRB) soon. Sources who revealed details and are familiar with the ongoing situation also confided that half a dozen other locations have also begun the process.

Citing stagnant wages, those who spoke with the Washington Post said that the recent efforts of Starbucks workers inspired them to start their own unionizing efforts. Amazon workers have also made headlines around the country for their efforts to unionize, though the E-commerce company has expressed anti-union views and engaged in union-stopping practices.

The tech company has yet to respond to the news of their employees reportedly attempting to unionize.

The report comes after Apple workers held a walkout in December and created a site that includes a letter to shareholders addressing what they can do to better support Apple employees, including recommended policy changes.

“The truth is that for many Apple workers -- a reality faced disproportionately by our Black, Indigenous, and other colleagues from minoritized racial, gender, and historically marginalized groups of people -- the culture of secrecy creates an opaque, intimidating fortress,” wrote the AppleToo group in a statement.
