That’s my situation at a Silicon Valley tech company. Nobody ever mentioned unions one way or another but I honestly have no idea what I could ask for that I don’t already get. We have good benefits, good perks, everyone works frok home, unlimited PTO that nobody tries to limit or work around (all we are asked for is to give a rough estimate of time we’ll be taking off during each quarter so that it can be factored into planning), good work environment, good pay.
Same for copyright law. The point was to give creators a few years to profit from their work before it goes into public domain.
