My little boy goes to a local private nursery 4 days a week as OH and I both work full time. The branch he curently goes to is in the town I work in and is part of a small chain of nurseries , all local. We moved house last year and there is a different branch of the same chain in our new village so we put his name on the waiting list and were told a few months ago that there would be space for 2 of the 4 days at the start of Sept if we wanted it, which we do. I told our current nursery this weeks ago in person and happened to mention to the manager yesterday that we had a settling in visit at the new nursery booked for next week. Today I got a message from her reminding me that I need to give 4 weeks written notice of giving up 2 of our days at current nursery - with 3 weeks to go until our new place begins meaning I will have 1 week paying double for 2 days. AIBU to have assumed that head office would treat it as a transfer and not enforce the notice period since they are both part of the same company? I'm feeling stupid but not entirely sure it's all my bad....
