Do teachers in the US have summers off?
Yes... but at the end of summer they mostly spend those last days setting up the classroom.
Yes, a lot of them work as rent-a-cops at the beach during the tourist season
Unless they have a summer job teaching, tutoring, or like my neighbor who captains sailboats for people over the summer
Most are unless they teach in year round schools. We have a lot of those cropping up in the states.
Yes, they have time to relax.
For the most part. My sister-in-law has worked at a zoo with the kids programs. She and my brother (also a teacher) took last summer off and traveled tho.
