This is a very complicated situation but I'll try and be brief.
Essentially I was hired into a new role at company X. For my role, I am responsible for the output of the company product. If I make a mistake, then it can mean losing an entire client.
There have been some massive red flags since starting. The person I have replaced has cut a lot of corners. There are none of the usual fail-safes set in place to catch mistakes which makes me feel uneasy.
Then, unfortunately, my managers adult son died of a drug overdose 4 weeks ago and I've been assuming his responsibilities. The first and only week that I worked with him, he was high twice at work. I've since heard that while he has been off his mental health has understandably not been good. He returns next week, part time.
No one has really spoken to me over this period, but I feel like I've been thrust into a position with a lot of responsibility. I don't want to come across as callous or insensitive, but this is so much more work than what I signed up for. Because I've been doing well with the new responsibility, the company seems happy to just let me shoulder this weight, but I'm not comfortable doing so.
We don't have HR that I can go to either.
I guess my question is how would you go about dealing with this situation? I don't want to up and quit, but I also don't want to be on the hook for doing a role that's way beyond my pay grade.
