I have plans for DS' birthday coming up which I have booked tickets and paid money for - they necessitate me having the weekend off work. I do shift work and not on set days so I can have theses days off as my normal days off or as holiday. There are plenty of staff who could cover those days and they have just taken on even more staff so there is no shortage of people wanting those hours.
I told my boss before Christmas that I would need those days off, either as holiday or just as normal days off. I gave her about 6 weeks of notice and have mentioned it several times since, when I booked the tickets and just in general conversation.
I have been signed off for a few weeks recently due to stress and depression, which she has partially contributed to with her general horrible attitude and bullying towards me.
I now see that she has me down to work that weekend, when I asked about it she just replied that I should have made sure I had it off before I booked anything. She knows that I've been signed off and the reasons why but she's still massively pissed off at me because of it and badmouthing me to other staff members. She also knows that I wanted that time off. Aibu in thinking that she has done this on purpose to spite me? Thus forcing me to chose between taking unauthorised leave and potentially risking my job and letting my son down on his birthday? Wibu to just take it anyway?
