Why don't all the people who complain that teachers have a cushy job with amazing holidays (I’m not sure anyone gives a duck what your DH would think, ex welder or otherwise.
I personally think teaching is the most important job there is. I also think being a teacher can be pretty tit depending on what you teach, the age group, the kids, the parents, the head, the school, the country etc.
And I absolutely know I couldn't do it, wouldn't do it. The pay could be 500k a year and I wouldn't do it. Reading just Mumsnet never mind other forums, social media, media and real life, I'm surprised there's any teachers left.
