Microsoft recognizes its first union as ZeniMax software testers organize

Microsoft said Tuesday that it has recognized its first union of employees in the software maker’s 47-year history.

Workers at airlines, automakers, schools and government agencies belong to unions, but collective bargaining hasn’t taken hold at large technology companies, where employees often receive high wages.

Amazon and Apple have not been especially accommodating to employees who have tried to establish unions. Last year, Microsoft said it would support approaches that would make it simpler for its employees to join unions.
