Work and hunt at the same time. Since most of my hunting is from a blind, if I need to work I'll bring my laptop and use my cell phone as a hotspot. Had several meetings in the blind before.
Otherwise when I call in, I don't give a reason.
When plant manager wanted to know why I was off, I told him it didn't matter. He just had to know that I wasn't gonna be there.
I use to own my a business and always explained ahead of time that I would be absent for hunting. Now I'm retired and can do whatever, whenever within reason.
