Apparently there's a massive nationwide shortage of bus drivers (the number I've seen reported or somewhere in the ballpark of 25% of what is needed) and with schools back to 5 days a week things are exacerbated immensely. Schools are offering full time benefits (for part time work) , sign on bonuses, and 20+ an hour for an entry level job
I assume this is a problem nationally, but if I drive anywhere even remotely near a school between 7-9 am it's absolute bumper to bumper gridlock since every parent is driving their kids to school (and schools are doing an absolute excrement job at keeping things moving by doing whatever it is they're doing)
