Good luck MsMA, because I think many people stay in jobs they don't really like, without looking for anything beyond in life (whether within or outside that job).
And after this, people often retire into ill-health, which may have been instigated by the job.
Many jobs are as you describe -
"they require us to do a lot in a very limited time and we're always short staffed"
People can be happier doing two such jobs for a few hours, rather than one such job full-time.
Talk just about anything you like...
