I was quite tempted not to post in this section as it can be quite rough on OP but here goes.
I took on a job at the beginning of December working 2.5 days a week. All in agreement these wouldn't change as me and DP Work childcare around ourselves as we can't afford the nursery fees around here. All good until now... my employers are also aware my partner gets his rotas 3-4 weeks in advance and is rarely in a position they can be changed. They have booked me onto a course on a day I wouldn't normally work and have told me to find childcare. I don't have any friends that are in the position to watch my daughter and all our family are 300 miles away.
