I work in admin and am currently managing about twice as much as the "limit" is set for someone working full time.
I did this during march-sept period as there was literally no choice also most of them went quite due to covid so it wasnt really twice as many.
Anyway now it has all picked up again and I literally have twice as much work as I should at full capacity. I am STRUGGLING to cope, I am missing things (making customers angry), then I have to spend ages resolving those and end up missing more things. It is a vicious cycle.
I am not paid well and if it wasnt for the current situation I would leave. I have raised this and we got a new team member but they are so scared of overloading him and scaring him off that it is making no difference to my work. It just means I have all my work and someone to train.
I have raised this too and they just say it will get better when he is trained, that will take months before he is signed off to work independently. I am not willing to keep working into my evenings and weekends because it is making me miserable.
Would I be unreasonable to say to them that I will do what I can in my hours and then thats it? If it all goes wrong my manager can resolve it? Sounds harsh but I am so stuck!
