NLRB v. John Gore Theatrical Grp.

Good. Gore and his "companies" are all disgraceful.

This whole scenario unfortunately points to a larger issue in the industry at large, but a small win is better than nothing.

Is there an article that explains the case in further detail?

I will try to remember to upload a copy of the decision when I am at my computer. The basics are that AEA started an investigation (presumably based on some information that Gore was flipping productions from union to non-union by transferring them to other entities that they owned, i.e., not legitimate 3rd parties.) An early step in an investigation is to ask the company for certain documents related to the transfer (something AEA has a contractual right to obtain). Gore dragged its feet and eventually refused to disclose, citing "confidentiality." AEA filed a complaint with the NLRB, the Board ruled that Gore's confidentiality defense did not hold water, Gore appealed to the Federal appeals court in NYC, and the court sided with AEA and the Board. At this point, nothing more is known. Generally, I find that unions don't investigate unless they are pretty sure there is a smoking gun, and employers with nothing to hide do not hire a top line anti-union law firm to dawdle and refuse to comply with a contractual obligation on a specious ground when they have nothing to hide.
