alt Hacker NewsIt really depends on the union, mine concentrate on less hours for a salary that follow inflation, parental leaves and a gold plated drug insurance. I work 32.5 hours per week in the summer, have 24 days off, 2 personal days and 12 statutory holidays; that's 36 paid days off !
Every time I've ever seen a tech worker's union, it's always some sort of political experiment rather than legitimately advocating for the interests of the workers it nominally aims to represent. E.g. the Google AWU-CWA union just did a bunch of political stunt stuff, no salary negotiation or anything useful to the modal Google worker.
