This to me, is the worst hill to die on. Take the booster on your days off. There is no reason the company should have to pay out sick time for something you can do on your own time. Getting boosted knowing you can't fly for two days and expecting the company to compensate for it is ridiculous. I'm 100% all for the line guys, but this is not the place we should be warring with the company. There does need to be a *modicum* of reasonableness.
