I am currently on maternity leave and just need some help with the below please. Just as I was about to finish for maternity leave I took a week off sick and came back to find out my colleague had been promoted to manager. Her new job was a none existent job and was never advertised. I was advised when i returned by whatsapp 'oh by the way I am now your boss' nothing was put in writing and I had no idea this change was happening. According to acas, you don't have to advertise a job however it is in your best interest to do so if you have someone under the protected characteristics I.e me as I was expecting at the time.
Since then her old job role has gone up for advert but I wasn't advised on this and the post has now been closed
Is all this allowed to happen? Should I have kept an eye out on the company vacancies on my maternity leave.
I really don't know how to deal with it all. It seems really dodgy to me
Thanks
