I worked for a classic MSP a while back, barely lasted 3 months. Such a toxic environment, tons of pressure to spread yourself thinner and thinner.
It was one of those places where you were expected to be there an hour early, stay an hour late, and work through your lunch.
Even though that's illegal, it was never explicit, just one of those, wink wink type things. But the workload was always so heavy, you couldn't stay on top of everything unless you were working 50+ hours a week.
And of course, all salary, no overtime or double time for weekend work.
I do internal IT now, much better. Trying to get my own one-person shop going to eventually be fully self-employed. Actually, it would be really cool to become a worker-owned co-op, but that's still a faint dream.
Lol I am so happy about this.
