*I suppose it shows your priorities to your child if you make time to meet them in person. It's only twice a year. Again, I don't understand why anyone wouldn't want to meet the teacher, unless they simply don't value their input into their child's life. They aren't just an inconvenience"
Firstly, keeping a roof over your head and eating is the biggest priority,
Secondly, not everyone can get leave from work at short notice. I can, DH has to provide 10 days, some people have to provide 6 months' notice.
Thirdly, there is a difference between not wanting to meet a teacher and not being able to.
Fourthly, it's not twice a year if you've got more than one child.
I don't see what the problem with a Skype call is, I work from home and talk to my colleagues via Skype all the time; and when I couldn't attend a parents' evening in year 8 the teacher called me or sent me an email updating me on ds' work.
