So, I've been working in my position for coming up to s year now. When I interviewed, I was told that in my position (Assistant Manager), weekend work would be minimal. Only a Saturday or Sunday here and there. Coming from a job where weekend work was mandatory, this was music to my ears, and greatly influenced my decision to accept the offer.
Since then, however, I've worked at least one day a weekend (usually both), every weekend unless I've booked it off weeks in advance. My manager, the one who writes the rotas, is only scheduling herself in for one or two (usually one) Saturdays a month.
How do I professionally let her know that this is no longer acceptable and I need to have at least some weekend off?
