Wella ctually DH's bosses were far more creative.
Firstly, Sunday was by far their busiest day: so they had extra coverage when needing it (should point out as well it was perm nights so sunday was really a saturday night IYSWIM).
So, others were all on 4 on / 4 off, so no more weekends on than before, just they had extra cover when needed and DH could do his work as and when: he was one of the specialists so able to dib in and out and quite a bit didn;t matter specifically what day it was done on.
But it is a balance of fairness- why is it fairer to restricts employment cahnces, or even the chance to keep a child in a family, than to restrict working choices for his colleagues? Surely it's less severe if his colleagues HAD been amde to do a slightly different shift pattern than the alternative consequnces to us / state finances of the other choices?
As it is DH is now self employed anyway, but nobody ever complained as they knew that frankly there were no choices involved for DH and he had worked those shifts without complaint for many years.
Funny thing is, he could not keep going- was impossible, was existing on 2 hours sleep a day when boys were home on old system plus safety issues- but he is wrong if he asks for flexible working, and now now he is self employed but low earning he is wrong to much of MN- at what point can he ever be right I wonder?
Although- I do think that incentives to promote flexible working should be promoted regardless of carer / parent status, job sharing etc can work for people in so many ways.
