I’m a dev and I won’t join a union. Two years is the maximum I would work at a company - big Google or tiny startup, on average it is 2 years per company (for me). It is quite common in the tech industry. I don’t want to be bound by salary ceiling based on seniority, like so many other unions work. I don’t want to pay union dues. There probably other reasons as well. Like heck, if you got canned, really what seems to be problem here? There are lots of job for techies out there. It probably won’t as much as Google did, but that’s fine, still it ain’t like there aren’t jobs out there.
