Hello. I am currently working with some people - laidback chidless men - who are really fun and brilliant but seem to have no clue about the realities of having kids, and who enjoy working 24/7. At the moment I only have childcare on certain days after school and when we are arranging meetings I am always very clear about when I have and do not have childcare and give loads of warning about my availability. I do this so that we have as much flexibility as possible. However, their style seems to be to let me know about meetings with less than 24 hours in advance, and often having completely forgotten or disregarded my childcare arrangements. I am not "below" them in status, we are equal partners, and I have tried to be really clear about not being that flexible, but they seem to not hear or understand, with the result that working with them is v stressful and often expensive as I have to get emergency childcare in. How should I deal?
