Me or dp at fault over childcare cock up? Who should have to take the time off?

[attheendoftheday]

So, dp and I have made a cock up with our childcare and one of us is going to have to take time off work, dp thinks it's my fault and I think it's his.

I am a nurse and dp is self employed. We have a calendar on the wall on which everything is booked. Dp text me (while I was at work and he was at home). Saying "Can you pick the kids up on x date. You are on an early shift. I have a meeting in London." I replied "No problem."

So, x date is Friday. I am not on an early shift, I'm on a late shift, so I can't pick up the children. Dp thinks it is not his responsibility to know my shifts, I think he led me to believe he checked the calendar.

One of us is going to have to take time off. Dp thinks his work takes presidence because he's booked a meeting. I think it's his turn as I've taken the last two times the kids were ill off as he always has "unmissable" things going on, and my ward's already short that shift.

Mumsnet verdict, who's fault is it and who should take the time off?

Thank you! I'm very lucky to work with a lovely bunch of people who are all really supportive over childcare issues.

I think the reason I was narked this morning was that this seems to equate to me taking the majority of the time off, which irritates me and makes me feel I'm taking the mickey out of my manager's and colleague's support.

Jengnr, think you have the nail on the head!
