One thing that sort of helps me know when I should quit a job is by looking at my employment as a business relationship between me and the employer. I have my aspirations and goals, and if the employment doesn’t work in my favour anymore, then it might be time for me to go. Things that can be “not in my favour” can be things like:

Not getting the promotions I’m expecting
Not getting the raises I’m expecting
Earlier promises or benefits have been rescinded
Workload and/or responsibility is increasing, but not met by raises or benefits
When the expectations of the employer and mine on my role no longer align

Thanks and praises are good, but those are free and are expected of a cordial relationship anyways. You don’t charge your friends for saying thank you after all.

Essentially, just like all relationships, if it doesn’t work out for us, then we should consider leaving that relationship, lest it eats at us. You can always argue with yourself on whether you should stay: maybe it’s just worse out there, maybe they haven’t crossed your bottom line, etc. We can’t use every logic in other relationships, but there’s a certain pattern to them.
