I can very much relate to your situation but unfortunately not sure what to do.

I’m doing some contract work on the side. Every day I’m like if this guy harasses me again I’m going to put my notice in go work for less money but unfortunately I’m not even sure what decision should I take since the job is high paying but on the hand the contract work is with the startup and pays less money compared to what I make

I wish economy was better so I could leave my toxic job.

Some managers are really pain in the ass
