"You work or I will make you suffer" is slavery.
Whether and do what degree the arrangement between the worker(s) and the pimp is exploitative is more or less tangential to that.
Mall cops certainly haven't enslaved mall owners.
All work is slavery.
I got up late today, so I barely have time to make pancakes and coffee before I have to leave for my day’s slavery.. if I’m late, I’ll have to do the slavery in my underpants at home until the morning meetings are over. Then I’ll drive to my slavery and be stuck there for 5-6 hours, with only lunch and snack breaks. Unless I need to take off early to run errands anyway
Most of the people here not only have the option of quitting, but a fair number could probably choose not to work for several months, or even the rest of their life. They certainly are not slaves.
Or a protection racket.
Or just fee for protection.
Depends on the specific situation in question. There's a wide variety of schemes that fall under the definition of pimping.
