Yes so women get 6 weeks at 90% pay whether that's £1m a year or £200k or £20k and men 2 weeks. After that most of us plummet to £112 a week which for someone on benefits is of course a goodly sum so it just depends on what you were on before.
"The rate of paternity pay is the same as the standard rate of maternity pay, which is £112.75 per week, or 90 per cent of the employee's average weekly earnings. "
If couples are planning returns to work and a first baby and the new rules come in then it may be something women want and men that the woman takes 6 months off and then the man the next 6 months particularly easy given how very very few women in the UK breastfeed beyond 6 months.
But if the both really do need the pay they both earn which was always our position then both getting back to work pretty fast is more likely to happen. If the wife earns a fortune and the husband not very much but the couple think a parent at home for a year is best then man off for longer might be the better choice.
