I'm a school bus driver and we're unionized (Teamsters) ... at least for now. Our contract states that if ever fewer than than 50% of the drivers are in the union, the contract is voided. A lot of the newer drivers are not signing up for the union because they don't want to pay the dues which are around $80 per month. We are surrounded by non-union school districts that pay their drivers about $8 less per hour and don't provide health insurance, PTO or a pension like we get.
In case this isn't obvious, school bus drivers are generally some dumb motherfuckers.
I grew up in the '70s. My parents limited us to one hour of TV per day, but I had friends who spent nearly every waking hour when they weren't in school parked in front of the television. Like, six to seven hours per day and more on the weekends. The stats back that up, too.
