The National Labor Relations Court has this power routinely in a case like this. When unions are getting your workers to decide to unionize and be represented by the union you, as an employer, are very limited in what you can do to discourage the workforce seeking representation. You can’t shut down branches picking union representation while keeping non-union branches open.
I don’t like it, but for fifty years at least this has been a hard and fast rule.
How many of Starbucks stores in the U.S. have been unionized?
That actually makes sense.
