I went back to my old job after almost a year on ML. I knew that there had been a few changes in my department while I was away but I didn't know that one of my senior colleages had left and I would be expected to take over her role as well as do my own job. This has created lots of extra work and I am sinking, I just cannot keep up. I haven't complained so far and don't know if I've left it too late. I understand that a company can't just sit still while someone is on ML but isn't the job they return to meant to be the same? There has been no talk of a pay rise to acknowledge the fact that I am now doing a lot extra - who should I speak to about sharing the workload out? It's a really small department and I don't want to be seen as difficult.
