Pictured: a Labor Dispute banner outside the Scientology Celebrity Centre in Hollywood. Anyone know what the problem is?

Scientologists do use a lot of "volunteers" to do a lot of work at their churches and offices and slave boats, which some unions might not take kindly to.

And there was, apparently, a dispute with the Church's outpost in Vegas last summer for nonpayment. If you're with the union bannering the Celebrity Centre, or know someone who is, let us know.

Update: It is not particularly earth-shattering! A reader who took a flier says the Church hired a contractor who subcontracted some construction job to a non-union company.
