Does a shop steward have to use vacation time to go to union training?

Whether a shop steward must use vacation time to attend union training depends on the policies of the specific union and the employer's agreements. In many cases, unions may provide paid time off for stewards to attend training, as it benefits both the union and the employer. However, if such provisions are not in place, the steward might need to use vacation time. It's best to consult the union's guidelines or collective bargaining agreement for specific rules.
