I don't want to sound unsympathetic, but a lot of these companies massively over hired over the last couple of years. While others were losing their jobs during the pandemic tech employees were in higher demand than ever. In fact, I'd argue the demand for tech workers has been so high over the last couple of years that a lot of people who really shouldn't have got a job based on their experience were able to do so.

I'd also note that the severance packages most tech companies have been offering their employees have been very fair, and with tech skills being almost universally valuable across industries it's not hard for good tech workers to quickly find tech jobs if they're happy to work outside of the tech sector.

If people want to form a union then fine, but I'm not sure what you expect. Spotify isn't profitable. With the cost of capital rising and a potential recession looming they obviously need to be financially cautious otherwise everyone at the company will eventually lose their job.
