If you lead worship at a small church, there is a good chance you only have one musician for each instrument (if that).
Then, when someone is sick or on vacation, you experience a bit of anxiety on how to make up for the missing musician. The anxiety then causes you to act out, giving the musician a hard time for not being there.
Eventually, a culture is created where everyone on the worship team is afraid to take time off. They don't want to suffer your wrath or cause you disappointment.
Although you may feel like this works out to your benefit (because they are not gone as much), it is actually counterintuitive. A team that feels strapped down and controlled is unhealthy.
At this point, you may be asking yourself, "But, shouldn't they be committed?" Why yes, yes they should. But, do not confuse commitment with perfect attendance.
When a worship team member is committed, they show up to rehearsal on time and prepared. Although they are there a majority of the time, they communicate with you (in advance) if they are not going to be there.
It is important that your team feels comfortable letting you know when they are unavailable. Otherwise, there is a good chance they promise to be there but then don't show up. And, as I am sure you would agree, this is much worse than knowing ahead of time.

Bottom line, going on vacation or taking a week off is not a lack of commitment. Life is meant to be lived and enjoyed.
Put your team at ease so they can enjoy being a part of the worship team. And, put yourself at ease by being flexible and not getting worked up if you do not have a full band. The Holy Spirit does not need a full band to make His move.
