I almost lost a contract with a city after union members complained that I was on their turf. Their non union bosses hired me for a job they aren't qualified for, or interested in having, to solve problems they'd been complaining about for years, but because I was using oxygen in their vicinity it became a legitimate union issue because of the language in their contracts. So, yeah. Unions do stupid stuff. I still support them. Kind of wish my contract had been cancelled, could have doubled my rate when they crawled back.
