Fortunately I don't have to come back. Yet.
However, when I do…
“Sure, boss, happy-ish to come back. However, you start paying me the minute I start my car. Still want me in?”
(PS: I live south of Austin TX, offices are on the far north side. It's a SOLID hour each way in traffic. You pay me? Sure. No pay for sitting in that commute? No way.)
