I think it depends a lot on the company - and also the department. I find there's rarely a problem with things like working from home because of childcare problems or child illness - or because the car needs it's MOT, or someone is coming round to check the boiler or whatever. I think all my male colleagues who are parents do quite a bit of childcare like that. At least one has a formal flexible working agreement to ensure he can be do the afternoon school run every day. Mind you, a manager did comment that a male Swedish colleague who took a year's parental leave wasn't really dedicated to the job... (Equality in the wrong direction.)
But I have had people assume I'm the secretary more than once (like anyone has secretaries these days, unless they're as high as God or so.) Pretty sure that's never happened to any of the men I work with.
They did change the "beware of men working behind doors" sign in the datacentre when I pointed it out, but I've still had supplier's engineers commenting on how unusual it is to see a woman in the datacentre. They don't mean it in a bad way, but it's just conversations my male colleagues don't have to bother with.
I got cheered when I arrived at a storage admin course at a vendor site, because so few women do it. It's appreciation of a sort, but my male colleagues don't have to be treated like a rare zoo creature.
I did pull my manager up when he said I am the emotional one in the team - ignoring the man who stood up and swore in a meeting - that's just passionate or something, not emotional.
I do feel angry at times, but I've never expressed it that way. My favourite is the colleague who said, "you can think logically because you don't have enough female hormones." He said it aloud, but I reckon there are plenty who think women are actually a bit crap (despite the evidence,) and just won't think of involving a woman on that project to give her a chance and so on. It's probably not even conscious mostly (unconscious bias), they just think of Dave and Paul before they'd ever think of Joanne. It means that when the company is doing good stuff like hold a session for women in leadership, some people won't be put forward for it, because you have to be nominated by your manager, and he doesn't recognise someone as a potential leader if they don't have testicle.
There is still a lot of that in IT - none of it that big a deal in isolation, but these micro-aggressions happen all the time, and it's death by a thousand cuts - it does take mental energy to ignore it, mental energy which male colleagues don't have to waste. (And some is not limited tech.)
But as I said, it does depend on the company. The last job I was looking at, their website showed one woman among all the men on their board and senior managers. I suspect it wouldn't be that supportive an environment. I don't know - I didn't proceed with the application because of their lack of women (not the only reason, but it was the main one.) I have been doing this for two decades - I'm tired of working with just men, and I want workplaces where there's more balance, and I am in a position where I can be picky about the jobs, so why not tell companies with too few women that's a problem.
Don't mean to put you off - all jobs have their downsides. But some companies are better for women in tech than others.
