For me it's the 6 week holidays. It worked well in a time where the majority of families were one income families. Where village communities were much more present. Grandparents typically lived close by and could help with childcare. When we had typical seasons before global warming kicked in.
I grew up in the eighties, summers were playing out all day. If my mum needed to go somewhere I went to my grandparents or a friends house. It was simple. Now it's just 6 weeks of childcare hell. Spending a fortune on childcare, expensive holidays, activities. It costs a fortune and I'm not convinced children get much out of the break anymore.
I think it needs cutting down to three weeks, And give parents two weeks they can use at their choosing (at certain time periods in the year)
What societal norms do you think are outdated?
