Until recently a lot depended on whether your face fitted at school, whether you were on the PTA etc.
I remember years ago asking whether my kids could have 5 days off so we could go on holiday as hubby was self employed and that was the only time he was not committed to jobs. My kids were never sick, never late for school and had excellent attendance.
I had to beg and plead with the head and he reluctantly allowed it yet I knew other parents who took their kids out several times a year with no trouble because they were on the PTA.
