I'm not going to argue for teachers being a 'special case' but there is a whole section on this website about education where parents are expressing very real and genuine concerns about decisions being made about their children by their children's teachers because their children's education is incredibly important to them.
AIBU is full of "AIBU to complain to the HeadTeacher?" "AIBU to be furious with my child's teacher about this?" "AIBU to expect more of my child's school?"
There are more complaints about teachers/school/education on here than any other profession (even more than drs receptionists
)
Because even the slightest distraction, error of judgement, wrong reading level, ill thought out decision, incurs the wrath of the parent - and rightly so because this impacts on the health, safety and education of the most important thing to them, their child.
People on this thread are responding to the suggestion, understandably, as other professionals, other employees, other workers who are comparing their own working life with that of teachers.
But applied to your own child's teacher you would want them to be working at their best. If you go to a cafe but they've taken on an older employee and they don't make the sandwiches as well as the other one did, or the service is slower, or they don't give the correct change, that is far easier to correct than realising your child has been in a class with a jaded, older teacher and has made no significant progress in maths because she just wasn't really on top of things anymore. (Happened to my son).
My mum is 62 and isn't a teacher, but it is apparent that she is not as "on the ball" as she was years ago. she isn't as quick in her mental reactions, she isn't as physically capable. She acknowledges that her performance at work isn't quite what it used to be, but it just means the same stuff gets done, just a bit more slowly and she doesn't put herself out to do the extras anymore. And that's the problem. In her job, it's not the end of the world.
