Since I started staying at home with the kids Bex has been promoted three times & has passed over 50 exams in work.
When I worked she couldn't do any of it, cos we, as most couples have to, had to do the usual leaving work early, doing condensed weeks, not travelling too far for meetings & countless other concessions that parents have to make to be able to do their share. She's also been able to take holidays & study days off work to study cos I've been there to look after the kids, which she wouldn't have been able to do as she would have need the leave for school holidays.
I could have refused & gone to work, or worked nights, as some parents I know do, meaning she'd have to bear much more of the weight of parenting as well as working full time, one or both of us would have been working term time only, & I highly doubt she'd have progressed from her job at that time.
My actions wouldn't have been unreasonable, lots of parents choose to work instead of staying at home, but if they do so it's obvious that the other parent will have to make the usual concessions at work which inevitably stall their career.
I find it hard to believe that you don't know this already. You must work with people who have kids who's other real also works & see the amount of time they have to take off, the regular early finishes or late starts, inability to travel for work etc that being a parent entails, & realise that reduces their chances at progression. I suspect you're just being churlish to troll.
I don't know why any of that is relevant to my position. It doesn't seem to conflict with any of it.
