Oh, by the way, thanks for ignoring the question. Here it is again, re-written so that it will take either 2 or 3 letters to answer.
Are you justifying the union thugs slowing things down by 60%, knowing that (a) they'll be paid 100% of their salary and (b) the dock owners can't do ANYTHING about it?
See #77. Short answer, NO. They should not have done that. They should have simply struck, IMHO.
