Need some advice please!
Bit of background:
I've just had my mum on the phone in tears. She works for a large supermarket chain (for nearly 20 years) and has just had an Attendance Review meeting. She has through no fault of her own, had a substantial amount of time over the last few years. All completely legit and backed up doctors/hospital. She has also had some dependants leave as she is the sole carer of my nan who has frontal lobe dementia.. Which is currently ongoing. She really has been through the ringer and her stress levels are almost at breaking point.
Anyhoo, she was admitted to hospital last month due to swallowing her dental bridge and it became lodged in her throat. She had emergency surgery and it was successfully removed. She was kept in for 2 days (which she doesn't work) and called in sick on the 3rd day as she couldn't speak. A manager was informed and it was put in black and white in her "welcome back" meeting. Due to her levels of sickness she was required to attend an AR. Most of her sickness is covered under DDA, but she was asked about this one day after her op and that it was unauthorised. My mum said it was and that a manager was informed. Her deputy manager said "Well I've asked her and she doesn't remember a thing about it" He then proceeded to tell her that she is lying about having the operation and then said he was adjourning the meeting because she was becoming too emotional until after Christmas and that she was facing a serious disciplinary/dismissal. My mum said that it was all listed in her welcome back meeting and that he should be calling the manager in to question her (she is at work) and that he should also have copies of her notes from the previous meeting, which he refused to do. She said that he knew about the current situation with my nan and that she didn't need this hanging over her head at Christmas and he refused saying he is following procedure.
Is there anything she can do? I've never heard my mum cry so much and I feel completely helpless 😩
