A potentially bigger deal for unions is Unite Here Local 355 v. Mulhall. The Court could find that a major union tactic — striking deals with management before organizing workers — amounts to bribery.

Mulhall will be heard in November. Dates haven’t been set for the others.

The cases underscore how much Big Labor relies on a favorable legal and regulatory environment. That’s why they came out so strongly for Obama twice.
