What if your unit makes you work while on leave? A colleague is getting charged leave but his shop is making him work. Does he have a say?

I'm not sure what the regulation is on this but I've never had it happen. But then again, whenever I've taken leave I've gotten as far away from post as possible.

Is your colleague going into the office to perform work, or is he/she just fielding phone calls from people in the office about work questions? This is material to my answer.

The unit SHOULD respect his leave and allow him to relax, however, in many offices, only one person knows things so when they are on leave, the office essentially shuts down. He also has every right to not answer his phone or email during leave without any repercussions.

As a leader, I know that I am always on the clock and will do my best to ensure that I am available around the clock but I shut off and ignore calls/vmails/ and emails especially when my commander reaches out to me.
