But can they stop the owner from shutting down the business?
I can understand the logic of calling this a threat, but I don’t see how they could stop anyone from just shutting down if a union is either voted in or installed by NLRB fiat.
The power that the NLRB has is pretty scary, the union attempting to form could just accuse you of not allowing a valid vote and presto chango, you're a union shop.
And to vote in a union, they only need 50% + 1. It was a fascinating day of study, that we'll all need to brush up on, and Texas is a Right to Work state.
