There would be generous state pay for both parents of under 3s. Enough to have a decent quality of life. The treatment of parents of under 3s is scandalous. The norm of one parent, especially the mum spending five days of the week mostly on her own with one or more babies is horrendous. Often isolated and largely unsupported doing an extremely important 24/7 job of caring for a tiny child while often iron-deficient, depressed and usually very sleep-deprived , yet unpaid and under valued; what sort of a way is that to treat parents?
Child-birth and caring should be paid in accordance with its value. Though I don't know how you would legislate for large families. There would be problems if payment was restricted to say, 2 children. If this generous pay was state funded and didn't cost employers anything maybe women would be penalised less for taking time off work and more parents would actually enjoy the experience and not want to work full time to escape the boredom/drudgery of unsupported life with a baby.
Part time jobs at all levels would be the norm. I really don't see why most senior positions (more likely to be done by men) have to be 5 day a week positions. I suspect it's because most men either don't want to spend time at home doing childcare and housework ( because they have been socialised to expect 'more' for themselves) and their male managers are comfortable being surrounded by other men like themselves who won't be expecting to have flexible working or to ever be the one who stays off with a sick child etc)
It seems so unfair that so many jobs are all or nothing. Very ambitious people with favourable circumstances, high energy levels and a lot of ambition would have more than one job but it would be more normal for both parents to work approx 3 days a week.
Breastfeeding would be normalised and celebrated. Bf skills would be taught well and in great depth and would be part of our mainstream culture.
Women would not feel the need to be more groomed and show more flesh than working men typically do. It would be normal for women to throw on a shirt, trousers and jacket. And high heels would not be allowed in the workplace. The concept of looking professional would include being clean and smart. End off.
Domestic task and the running of the household would be shared equally by men and women. Men would take pride in doing a good job of sharing the running of the household and taking responsibility for thinking about it. The terms husband and wife would drop out of use. Spouse or partner would be the norm. There would be no 'wife-work' anymore if there was spouse-- work.
There would be equal representation of women and men in films, music and literature. The norm of male-dominated entertainment would be overturned. It would become unacceptable to revel in a diet of violent films and tv where most of the women have subsidiary roles, unless they are very attractive, and even then. People who watched mostly media like this would be seen as dinosaurs with dodgy preferences.
The problem of male violence would be recognised, researched and dealt with.
