One job required certain attendance conditions for promotion. So I busted my butt, didn't miss a day, for six months. Then got told my "revenue per call" was too low for a technical support job and, after a panic attack while on the way home from work, I quit.
Revenue per call, on calls related to fixing broken Internet service. Sell people even more service that won't work. And 3/4 of the calls were service down due to non-payment.
At Charter Communications around 2012.
