Bingo.
Our school board is filled with ex-teachers and administrators who needed a paid position with benefits after being forced into retirement. The school board position should be voluntary so it is truly about public service. Unfortunately, ours pays $50,000 a year so these folks look at it as employment. The results are predictable.
And its really bad if it pays a pension. If that is the case. You can expect teachers to always get the job. A pension for them is worth maybe 500K for four years. Especially if those teachers need to get up to a 30 year cap. And they can do it without lowering their pay. Sometimes they have a clause which allows them to count their average final pay as the top 3 years of the past 10. That allows them add years without lowering their average pay.
