If you have a team of people reporting up to you, and your office is closed today (because of President’s Day) please don’t send them any email.
 
I know, I know, you are probably using the day to catch up on things. That’s great. Save all those emails in your draft folder and press ‘send’ tomorrow morning.
 
If you email folks on their day off you are undermining their ability to recharge and signaling that they need to be ‘on call’ 24/7.
 
This tips holds for sending emails after working hours too.
 
Part of good Executive Presence is managing other people’s anxiety. Paying attention to how AND WHEN you communicate with your team is one way to keep the stress level down in your office.
