I feel bad for your son and hope the year goes well for him but I don't think parents should be allowed to be employed by the school their child goes to. I see it quite often (maybe because I live in a small town) where children whose parents work the school rule it. They are never disciplined, they get to bully other students, get physical, talk back, do whatever they want and no one bats an eye.
Edited: yeah but right away you wanted them to bend the rules (march deadline) what is that showing them? Wou work for the school so the rules shouldn't apply to you should get special treatment. You should not be upset they denied you. It's your kids that they will be treated the same as everyone else even if you work for the district. 2 thumbs up to your district or playing fair! Most schoold have next years budget already planned for the upcoming year befores school even gets out. It costs the town/city more money to have your kids go o a school outside their schools area.
Have you considered homeschooling? If it's a financial burden to have at a different school from you would it be more cost effective to stay home with them and then you wouldn't have to worry about your son.
