One Region contest in the Fall (Marching)
Two in the Spring (Concert)
Fall/Winter Concert. Spring Concert. Pre-UIL concert.
Eleven or twelve football games (since EVERYONE makes the playoffs).
Three parades - one in the fall, one in the Spring. Add a third for either Homecoming or a County Fair or some other nonsense.
That's .. 21 total "extra" days, all between 3 and 4 hours worth of time, added to your contract. And I don't know about you, but my Region Marching and Region C&SR are usually during the school day, so those don't really count - but let's leave the days in in case you choose to go to an invitational marching contest.
If you take an excessive five hours per event, that's 105 extra hours. Divide by your 40 week school year and you're spending an average of less than two and a half extra hours per week at school.
It CAN be done. And that's with the BUSIEST possible schedule, which doesn't include marching band rehearsals, admittedly. Many small schools do one or two rehearsals a week - 3 hours on Tuesday nights, for example. Times 10 weeks: add 30 hours. You're at 3 hours and a few minutes on average per week.
If you teach JUST MS band, take most if not all the football games out, marching contests out, and everything else HS band related - you're adding maybe ten hours total of extra time a year.
The fact is - if you think you're working too much, find another job. HS Band is a huge commitment. If you aren't willing to make it, do something else.
