My grandfather had a wood burning stove as his only source of heat for YEARS. Refused to swap to gas.
One day, we distracted him with some friends and removed his stove literally behind his back. The next day, he was complaining he hadn’t done it 40 years ago.
So maybe just do it when they’re distracted.
Are you talking about calling in sick, or taking PTO? Because I’ll be damned if anyone is gonna jump my ass over spending my earned time off as I please.
If I call in sick, I usually just stay at home and freak out all day about someone from work coming by.
