In my last job I managed a group of dedicated women. Two had kids in primary school. One was a ‘childless’ woman in her late 40s.
The mums had demanding roles and demanding kids, so there was flexibility for them to stagger working hours, work from home and generally do what they needed to do to keep their families functioning.
My ‘childless’ employee was a tireless worker and generous soul, but she had aging parents and quite a bit of responsibility for helping them out, especially when serious illness hit her father.
