WORKERS at an Apple store in the United States have become the first employees of the tech giant to unionise in the country after a vote in Maryland on Saturday. 

Staff at the Towson shop voted 65 per cent in favour of trade union recognition with 33 per cent against as they demand a say on wages, working hours and health and safety. 

A group of workers wrote to Apple boss Tim Cook last month saying they wanted to form a union at the store.
