Just a perk of the job that I'm completely jealous of!
It is a perk that is unpaid. So it is a conscious decision one has to make: summers off, but no pay.
Regardless, as has been said again and again, teachers are not whining about salaries. Just setting the record straight.
Unfortunately, way too many parents think that the teacher's day ends at 3. Summers off or not, the problem is that so many parents think that teachers have a lot of free time during the school year, and that if they are not giving special snowflake special attention is because they are lazy, which is the furthest thing from the truth.
My wife is a high school teacher. Her day starts at 7:30 4 days a week, and one day a week it starts at 7. She teaches 5 classes a day, plus study hall and detention. School is done at 3:15, and she has to stay an additional 30 minutes every day for after school tutorial. Once a week, she also has faculty meetings at 4. So one day a week she gets home at 5:30, and she gets home at 4:15 the others. Once every two weeks she has to stay an additional hour after school coordinating the extra curricular activity she is in charge of. And all of this not counting either planning or grading. During the week, usually she does planning and grading until 7 pm. And all of this without including weeks when she attends plays, parent conferences, sporting events. Now, she doesnt complain about pay, hours, or anything like that.
What she DOES complain about is when parents think that she has a lot of free time and therefore should be willing to meet outside the scheduled tutorial hours to tutor their kids individually, or when they get upset because she can't make individualized lesson plans for their special snowflake, or when they expect her to meet with the private tutor to explain upcoming lesson plans, and so on.
Just look at the OP: her son is happy and doing well in school. Isnt that the basic objective of a good teacher? How can the teachers be so horrible if the son is happy and doing well? Unfortunately, so many parents lose track of that and demand individualized lesson plans, rules, evaluations, etc. Something most teachers would love to provide, except they teach dozens if not hundreds of kids, and already work very long hours during the school year.
As for the rules, unfortunately every parent wants exceptions made for their kids, and harsh punishments for every other kid. When schools are being sued daily because of any type of bullying, harassment, etc. that goes on in schools, dont be surprised that the schools will adopt very harsh punishments to deal with that.
