COFFEE giant Starbucks was prevented on Tuesday from impounding ballots cast by the company’s workers on whether they want union representation.

Starbucks Workers United, a union of Starbucks baristas organising in the US city of Buffalo, welcomed the National Labour Relations Board’s (NLRB) decision to dismiss Starbucks’ request to halt vote entirely.

The NLRB’s ruling, the union said, signalled yet another win for the workers.
