In the city of San Jose a couple years ago - the Firemen were given the choice of taking mild cuts in benefits or loosing 80 some odd fire-fighters. They took the loss of jobs as the preferred solution, then gripped about it!
I’ll bet layoffs were seniority based rather than merit based as well. Unions claim to be about brotherhood, but throw the new guys under the bus and protect the senior guys when push comes to shove.
