And what would those jobs be, retail or hospitality? Do you mean minimum wage jobs that no one with a decent education does?
I worked in a shop for a while, for minimum wage, with a PhD.
On the whole though, most of the people I meet who say they have to work weekends are bar staff, chefs or waiters/waitresses. Those are proper jobs, thems are.
You sound pretty awesome, a real high flier with talk like that. That or a puffed up self important waste of skin. Forgive me, sometimes it's hard to tell the difference.
