While technically true, the enforcement is up to the Department of Labor. Do you honestly believe that Puzder (now Acosta) is really going to enforce these rules? It's the whole reason they were chosen for the position in the first place.
No, enforcement is not up to the Department of Labor. If you're terminated for organizing and protesting against working conditions, your recourse includes the courts.
People should, of course, talk to labor lawyer before organizing. Tech Solidarity is working with several now, and collecting employment contracts from the best-known tech companies in order to provide standardized organizing advice.
Really? Alright I'll bite. They only promulgate the regulations that are enforced. And if you're being pedantic enough to insist it's the DoJ, then my point still stands under one led by Sessions.
