(Reuters:) On Saturday, Apple Inc (NASDAQ;) workers in Maryland voted to become union members. This is the first time that Apple Inc’s retail workers have unified in America.

The union stated that more than 100 Towson, Baltimore workers “have overwhelmingly voted” to join the International Association of Machinists and Aerospace Workers.

They wrote to Tim Cook in a letter expressing their support for the Coalition of Organized Retail Employees.

They wrote, “This is not something that we oppose or create conflict between our management.”

Responding to Reuters’ request for comment by Apple, a spokesperson said that Apple had “nothing else to add” at the moment.

We are seeing a lot of U.S. businesses, like Amazon.com Inc. (NASDAQ:), accelerating their unionization efforts. Starbucks Corp (NASDAQ:).

Apple workers in Atlanta that were trying to join a union withdrew their request for unionization last month, citing intimidation.

Last year, Apple employees (both current and ex-) began to criticize the company’s work conditions online using #AppleToo.
