Chance are you’ll be considering next semester all throughout the Christmas Break (although we should all remember that church-based college ministers may have an entire “other ministry” during this time!).
In any case, as you (and any staff) are making those plans, why not keep your student leaders looped in? It’s as simple as an email or text soliciting their input, and suddenly you’ve reminded them of their opportunity and highlighted their ownership.
If you’ve truly designed a student-owned campus ministry, why work without them when they’re “out of session”? U.S. Presidents may have that prerogative, but there’s no reason a college minister needs to!
