My work is cracking down on people that "just decide" to work from home. Sick? Take PTO. Sick for while? Get a doctor's note. I'm going to miss the personal responsibility and freedom that afforded you. I've had nights where I've gotten barely any sleep and working from home is much better than getting dressed and driving in. BUT at the same time, I can't remember the last time I used up my sick time, let alone my vacation time, sooooo, I guess they'll just be getting less productivity out of me?
On the flip side, now that I'm a manager, I understand the enforcement. One of my underlings is this walking bag of germs and malady. Fine one day, out sick the next, fine and back in the office the next day. Has back, foot, and knee issues. Has been out multiple times just to repair his car. He has already used up his sick time for the fiscal year that ends in July. Now he's pissed that he's going to have to carpool with wife instead of working from home when his car needs repair.
I know I'm at the opposite end of the spectrum, I have tons of unused PTO time and I don't mind using vacation time when I'm sick because I like my house. But I also don't see what the proper middle ground is. I'd like to be able to trust people to work from home, but I know myself, I am not as efficient when working from home, and I bill appropriately.
