My manager (director of IT support) is asking how I’d like to set up weekend coverage for emergency tickets. I have some ideas, but wanted input on others who have dealt with this.

Currently team: 3 service desk employees plus me, 4 people total. Covering tickets for around 350 people. In our immediate area.

My thoughts: rotate on call so each person has one weekend a month to cover for. Only tickets being dealt with on the weekend are emergency (my boss and I agree on this. I’m asking we get a concrete definition of emergency). I’d like to limit the timeframe over the weekend we’re responsible for, but I feel emergency tickets will mean coverage 24/7. I’m also considering checking into additional compensation to cover the additional hours they will need till be available.

Thoughts, advice?
