To ask my employees not to contact me outside of my working hours?

[rathernotshare]

Back story. I'm a manager in a large company. We are being briefed and briefed about looking after our employees welfare while they are working from home. My team is working all hours of the day to fit around their lives. I'm continuing to work office hours so that they know when I'm working, and we all have some kind of overlap. However I'm getting calls at all hours of all days and I can't cope with it, but it's being rammed into me that I need to support them. Am I being selfish? Can I ask them to back off or would that make me terrible?

@rathernotshare if u r too nervous to make a decision by urself, ask hr how best to handle this. i dont understand why u arent putting ur foot down and saying this is a personal number, please dont call out of hours.

Can you not put your phone on DND with a few excepted numbers?

Of course you can still have boundaries.

Put the e-mail footer suggested above on your e-mails
Put an message on your phone explaining you are available for work calls between 9 and 5 or whatever you want to say.
Put your phone on silent and glance at it every now and then if you think friends / family are likely to be ringing you (or get them - family / friends) to text or email you first, with a different notification.

There's all sorts of ways of doing it, but you cannot be expected to be 'on duty' 18 hours a day to fit in with everyone else's strange hours. It doesn't sound as if your team would be completely stuck for work for 4 hours if they do want to ask something.
