not always (in tech sector). you could end up in a place that is worse or the same level of bad, also. its happened to me a couple of times already, though the opposite also has.

also, conditions in the sector as a whole will change, as more "belt-tightening" is imposed, as a result of an already stagnating industry that is relying more and more on extracting money through subscriptions and is less able to deliver on innovating tech promises that it was able to in the past.

i think the golden age of tech sector unionization is yet to come but will probably happen in the next 20 years, similar to how many telecom and electrical companies got unionized in the US in the last century, but only time will tell of course. that said, imo, we should strive to do what we can to push unionization in this sector along at all points in the process, even if that means doing so at another job and not the current one. hell, google workers are already doing so, as are grindr, kickstarter and some other places
