My previous job - I had nothing to do. I was watching Netflix. In my current job, I have so much work that I don’t have time for eat lunch.

Neither of the two situations is good.

I’d suggest looking for another job. Life is too short to schmooze. The other option is to spend the extra time learning. Most important - don’t feel bad about getting paid for not doing much work. It is not your fault, it is your employer’s fault
