to not get employed ever again

Always agree on compensation/salary before starting your work.

Companies don't give a fuck about you anymore

Yup. At my last job, I did my best to produce quality work, I got an award for making zero errors in a year, and I was one of the go-to people for new employees to ask for advice. I trained new team members, even while I was still a temp myself. Eventually got told that I was joining the team that dealt with all the escalation emails. I only knew how to work on 2 of the many types of products that went into that folder, but it was mandatory to work every single email that went into that box, 2 hour shift, every email had to be answered by the end of the 2hrs. I also only had a single 30min super quick "training" on how to even answer the emails (really complicated template system, which I still did not understand by the end of it)

I told my manager I wasn't comfortable working in that box, considering they never trained me to work on most of the other products, but she ignored me and said I'd figure it out. Luckily, I only had to do it once, then they delayed my actual start date for that task, until I got laid off (along with most of the rest of my team) 3 months later. YAAAAAAY. :|
