DH and I both work full time, Monday-Friday. Both commutes are about 45 minutes by car. DC are 14 and 11 so walk themselves to and from school.
I initially went part-time when I returned from mat leave after having DC, returning to FT when DC2 was 2.5. Not my choice, as exH walked out, but it certainly helped my career.
I'm fairly senior and work with an international team so can be flexible about my start and finish times. I have to be in the office 3 days a week but I get to choose which days. On office days, I usually leave the office at 2.30-ish to beat the rush hour traffic, then finish the working day at home. If I have a meeting I need to stay for then either the DC fend for themselves for a couple of hours, DH comes home early or I ask my parents to babysit until one of us gets home. That's pretty rare though as most of my later meetings are with colleagues in the US so I take them at home/on the go.
I extend the same flexibility to my team, several of whom are working parents. As long as the work gets done and to a high standard then I don't really care how they structure their day. This seems to puzzle new starters but has worked well so far. I used to work for someone who rarely came into the office but denied all ad-hoc WFH days and was vicious with anyone who wasn't in on the dot. It was awful for morale and as our work allows the flexibility I prefer to treat everyone as grown-ups.
If I wasn't as senior, worked for a smaller company, they weren't so relaxed about working patterns or the DC were much younger then I wouldn't be able to do this job. Previously, I worked for a company in our town to be close enough to do the nursery/school run. Once DC2 was old enough for after-school club I was able to switch to a company further away for a 60% pay rise. I fit in a full day's work by 4pm, then run the DC around to their after-school clubs, make dinner, put DC2 to bed and collapse on the sofa by 9pm. I'm tired and overweight and don't get as much exercise as I'd like, but I could if I really wanted to. I'm pretty happy!
