Across the retail, service and tech industries, Apple store employees have voted to unionize.

In Towson, MD, the National Labor Relations Board must confirm the union's membership.

NLRB's regional office, which was closed late Saturday, handled initial questions about the vote.

The Associated Press called Apple's spokesperson Josh Lipton to decline comment.

Amazon, Starbucks, Alphabet, and REI have recently established numerous unions after decades of decline.

IAM and Apple employees who wish to join the union notified Tim Cook last month.

The Coalition of Organized Retail Employees, or CORE, aims for "rights we don't have today."

CORE members celebrated this historic victory in a statement by IAM International President Robert Martinez Jr.

Other labor organizing efforts in the country have been rebuffed, including Apple store unionization.

The first unionization attempt by Amazon in its history occurred last month on Staten Island.

The coffee chain's workers in Buffalo, New York, voted last year to unionize with dozens of Starbucks stores in the U.S.
