Was told once that I look like Jonathan Davis from Korn. I don't see it myself.

If this was volunteer work then that's one thing. If it was paid labor then I see nothing wrong with this. Natural catastrophe or not, union agreements need to be honored. The union I used to be in had an article in their agreement which stated that any work that can be done in house must remain in house and be performed by members of the bargaining unit. This was for good cause because if not for this the union would have no bargaining power knowing that the corrupt-*** company could just lay us off and bring in outside guys or use their own corporate employees to do our work. It's not even completely a matter of money. Agreements are highly detailed documents which outline the working conditions, how employees are to be treated, what the company and the workers can and can not do, etc. This document is reviewed, revised, and voted on by both sides before it is signed and once signed must be abided by. If the company is allowed to get away with violating any part of the agreement then it is a worthless piece of paper and there might as well not even be a union.
