There's a big thing in the UK at the moment about companies publishing their gender gap (i.e. difference in average hourly rates for male and female employees). Personally, while I think it's vitally important for all companies to address this and do everything possible to prevent sexism in the workplace, I think there are too many factors that are outside the employer's control to blame everything on them.
For example, I'm a single mother. I didn't choose to be a single mother. I'm not going to say why I left my ex (I'm not one for airing dirty laundry in public), only that if I did tell you, the typical response would be "omg I can't believe you didn't leave him much sooner". Being a single mother means that I've had to take a job that's compatible with looking after children, which basically means I'm earning probably less than 50% of what I'd be earning if I did the professional level job I'm qualified to do. I was unable to stick with this job due to the hours/workload being unmanageable and incompatible with looking after children. It got to the point where the stress was affecting my health so much that my doctor told me to change careers. I also was very unhappy about never having enough time or energy to do anything with the kids beyond the basic things such as keeping them clean and fed. There was no other parent around to take up the slack and I wasn't willing to risk my kids' future mental health. A single parent is both the breadwinner and the primary carer and it is impossible to be both at the same time without one taking a back seat. And, due to the fact that children are little people who are completely dependent on you both physically and emotionally, it can't be the parenting that takes a back seat.
Single mothers, however, are near enough universally shat-upon by society in general, seen as scum and a drain on society. Assumed to have become single mothers by sleeping with millions of men without using contraceptives so therefore have brought it all on themselves, seen as unintelligent, chavs, irresponsible, crap mothers, unemployable, the reason why society is going down the pan... you name it the stereotype is out there. It's so grossly unfair because we're actually taking on the responsibility of two people at the same time. Even when the absent parent contributes financially it's only a small amount. My ex pays what the CSA (government agency to make sure absent parents support their kids) expects of him. The amount of money is about three quarters of what one week's grocery shopping costs... and it's a monthly payment. Yet according to all the prevailing stereotypes, I'm the lazy, chavvy, irresponsible one. Even just typing the words "single mother" makes me feel like everyone's going to judge and look down on me. (I know not everyone thinks like that, but the negative attitudes are hard to miss...)
So if the relationship breaks up, the father's free to pursue his career and earn lots of money - if he's responsible then he'll make the maintenance payments, while the mother has now got severe limitations to what she can do as a career and how much money she can earn. I know one single father, a widower. He's faced the same restrictions and difficulties that single mothers face, plus the added difficulty that people are even less understanding of men facing these difficulties. It isn't just women that are affected, but women are disproportionately affected because so many more women than men are in this situation.
I have now got a 9-5 office job. My childcare provider covers 8am until the start of the school day, and from the end of the school day until 6pm. This means that I can't do any overtime, unless I do a half hour lunch and squeeze half an hour overtime in then. It limits what jobs I can go for within the company. They're big on helping employees progress up the company and my boss (who's female) has suggested certain higher up roles that she thinks I'll be good at and should go for. It'll have to wait until both my kids are old enough to get themselves to school and back alone and not need any childcare though. So right now, I'm not really helping my company with their equality stats, and it's not their fault at all. I don't see any sexism going on at work. There are plenty of female employees at all levels (albeit the CEO is male, but there's only one CEO). I feel confident that if I went for an interview for any position within the company that I wouldn't face sexism and they'd employ the best person for the job. But it's me that's not going for the interviews in the first place because I can't commit to the extra hours.
There was an article in one of the major UK news providers recently (probably the BBC but I can't remember) about a young mother who'd just graduated from uni but was unable to find any professional level jobs that would allow her the flexibility to pick up kids etc, so she's ended up with a minimum wage entry level job.
IMO one of the biggest thing employers can do to address the inequality is value parents and parenting a lot more for the fact that we're doing our bit to raise a mentally healthy next generation, and allow parents (male and female) flexibility, part time roles and job sharing at all levels, not just entry level jobs. There is legislation in the UK that outlaws discriminating against parents and part time workers, and against women for having a baby, but at a practical level, women still end up not getting jobs or not going for jobs in the first place due to childcare commitments. And cases where women have babies then their career progression ends still happens... it's illegal to fire someone because they got pregnant but that is only the tip of the iceberg in terms of what actually limits primary carer parents from progressing.
Men aren't going to fix this. Women need to start in their own lives by not marrying into it, and opening the dialogue with their kids, girls and boys. However just because a woman stays home and runs a household doesn't mean she isn't her husbands equal. Just because I don't earn financially what my husband earns doesn't mean anything, we share everything 50/50 meaning that OT bonus is half mine, why....because without me he couldn't work that over time and he respects my role in his ability to work the OT. That's respect. He treats me as his equal, we make decisions together.
I think it's vitally important that society in general reevaluates its opinions towards parenting in general. Why is it that a woman who chooses to work less (or not at all) to focus on the kids is seen as doing something negative? When my kids were little I was berated online by a male "feminist" (he called himself that) because I was at home with the kids. He called me all sort of names. I gave him what for and said that the version of "feminism" he was calling for was still men telling women what they can and can't do. It also ignores the fact that someone has to look after the children! This ties in with men's rights... look at all the toxic masculinity attitudes towards men who are the primary carers or stay at home dads. Why? Historically it's been seen as "women's work" - low status, unimportant, invisible, stuck at home, etc. While it's essential for feminism to have a strong focus on enabling women to succeed at all levels in the workplace, it's also important to stop debasing motherhood in this way (which inadvertantly debases fatherhood should a man be the primary carer because he's seen as lowering himself to do low status women's work, but fatherhood when the man goes to work and leaves the primary caring to his partner isn't debased). Women are always going to have babies and if women stop having babies our species will go extinct. Good parenting is vital for society and neglecting children results in long term serious mental health consequences for the children and the adults they become, and future society in general. Why doesn't society already respect mothers and primary carer fathers far more? Being the primary carer should be respected for the bloody difficult and extremely important job that it is.
This lack of respect for parents influences the attitudes of employers. Like when they see someone leaving early to pick up the kids as "slacking" and "not being committed to their job". It's not a lack of commitment. It's having two major responsibilities in your life and trying your hardest to juggle them both. Employers should understand and respect that.
These people were raised by someone... their mother or someone else who was their primary carer, in most cases, a woman. Why isn't there more respect for primary carers? Why is respect only given to the parent who earns the money, not the other one who makes sure the kids are properly cared for while their partner's out earning money? Why are single mothers seen as the scum of the earth when they're actually doing both parents' roles?
