In my mind the two are not even remotely related. I see no reason at all for publicx sector unions. None at all.
Well then, I guess it is obvious you have never been a public employee....like say a school bus driver....most of whom work part time and make about $12 a hour in Oregon. Oh and part time means you drive at 6:00 a.m. in the morning get a long unpaid mid morning break and then drive again in the afternoon until about 5:00 p.m. If you are lucky you'll get an extra trip, like taking a bunch of rowdy football players to their away game and then bringing them back when they are either in a foul mood because they lost or losing it because they won. You might think the benefits are good until you discover that because you work parttime, you are not eligible for benefits. Well, you do get summers off, unpaid. You'll need another job for the summer because school employees do not qualify for unemployment during school breaks.
Or maybe you rather be a school custodian. Again most postions are partime and start at around $12 an hour. You won't mind cleaning a urinal that some kid took a shit in, will you? When you get done vacuuming about 10,000 sq. ft. of carpet in about three hours, you can go out and police the grounds where homeless folks have smashed their beer bottles, left their used condoms for you and pissed on the school steps.
I could describe each classified school employees job for you....maybe you'll find one you like. Regardless of which one it is though, don't expect to get rich doing it. As for job security, you can forget that too. With budget cuts, may school districts are looking for volunteers to replace the folks they laid off last month. Care to volunteer?
And this is with public sector unions. Imagine how good it would be without them?
