Yeah, December sounds good. You've hit the spot with this burned-out professional. I need a vacation badly, but I have clients. I can't go on vacation. I run my business successfully.
Flexible time helps employees to phase their worklife and understand priorities of life and work.
If the problems extend beyond a day without solutions, leave them aside for another day. This lets you look at them afresh and have a different insight. Let people plan their vacations as they want and as per their convenience. I work very hard eight hours a day, five days a week. I have plenty of time to sleep, shop, and recreate on my time.
