Strictly speaking, it isn’t motherhood that’s the protected characteristic, it’s maternity. Which I think the guidance sets a time limit on. I came across this when researching the protection against discrimination for breastfeeding mothers, and the government at the time relied on EA2010 to say that breastfeeding mothers are protected from discrimination in law, so that they wouldn’t have to bring in specific legislation to provide that protection.
So “fatherhood” wouldn’t be the/an equivalent protected characteristic to “maternity”.
To argue for the necessity for a protected characteristic (other than, ‘wah! not fair!’), there would be a need to come up with something more narrowly defined than “having offspring”. Maybe something around the sleep deprivation early days? But other than that it’s not obvious what the material difference would be between man with baby offspring / man with toddler offspring / man with teenage offspring / man with no offspring to justify discrimination protection legislation.
Sorry got a bit convoluted there, feeling tired today.
Just to add, if “having offspring” were - in effect - to be a protected characteristic, then it would be very difficult to argue that “having caring responsibilities” shouldn’t be.
But that would get into quite a different debate though, at that point. About the nature of the PCs - which are essentially individual personal characteristics (age, sex, race, disability) currently - instead moving into the field of domestic/ social situations.
Perhaps the incorrect PC in that strategy document is someone at Nottingham Council trying to make the case for men to be treated as if having a pregnant partner is no different from actually being pregnant. Perhaps someone in Nottingham Council thinks it’s an outrage if female employees get time off for ante natal appointments and male employees don’t. I guess that’s as plausible as being too lazy to look up EA2010.
