I'm arguing with someone that claims employers (EDIT: in the US) cannot tell an employee to work at a store the employee doesn't want to work at, or transfer them to an office in a different city. He seems to think this is impossible because it would be literal slavery, ignoring the (I thought) obvious fact that refusing would lead to being fired, which is a choice that actual slaves don't have.
So I'd appreciate any stories about “You can go work at this other location, or find another job with a different employer.” I have pointed out the thousands of articles on people working from home during the pandemic being told to return to the office when they don't want to, but since this person seems to have trouble seeing when situations are analogous and when they're not, I'd like to just avoid the “But that's different” response.
