I'm mostly on the side of the teachers in this thread, but things like this tend to lose me.....
In Kentucky, I currently know 5-6 teachers who work full time jobs during the Summer. at a call center, as a restaurant server, doing taxes, mowing lawns, construction. I even know 1 teacher who hasn't worked during the Summer, but is a bachelor and has spent his Summer overland camping in his Jeep for 3 out of the past 5 Summers.....going all over the US.
In Tennessee, I currently know close to 10 friends/family who routinely work 30+ hrs/wk during the Summer. At the co-op, as a car mechanic, mowing lawns, running a daycare, at a Faber-Castel pencil factory, at a make-up factory, a Ranger at a National Park out in Colorado, construction.
And a good portion of those teacher friends/family of mine that don't work say that they don't do so because they want the time off to recharge or spend with their kids.
