Send an e-mail to the admins you oversee, commending them for their excellent work on a project or what they’ve accomplished for the week, and cc your boss.
By sending an e-mail, you accomplish several things in one efficient step:
1. You communicate your successes. You show what a good manager you are by giving credit to others.
2. You improve the morale and productivity of the people you’ve just commended. All at once.
