We had a voluntary parting scheme end of last year. One of the people who took the redundancy was our HR/Payroll administrator. I was in another part of the finance department happily working away when I was asked to take these this persons role on and someone else was hired to do my job. I only work 22.5 hours but since I've been doing this I've been working on average two or three hours more trying to get my head around it. Training is sub par at best. Nothing is documented. I'm trying to learn all the tax terms which I was clueless about before this on my off time. Its all consuming. I'm stressed going on two months now. How long should I give it before I pull the plug and just give my notice? I've already spoken to my manager and relayed all this to her but she has made the excuse that a family member of my trainer is ill but on the mend now so her training was probably not great these past few weeks. But should improve now the family member is on the mend. I've said I can probably manage the payroll side but the HR side just pushes me over the edge. I am getting countless emails and I don't know how to respond as I haven't gotten any formal training on it whatsoever. There are huge spreadsheets to maintain and it all just looks so daunting. My manager doesn't seem to want to hand over the hr duties to anyone else as everyone else is so busy. I feel I'd be letting everybody down if I handed my notice in now. I'm so unsure about everything and in panic mode and wondering if I should just slog it out or just quit now for my mental health sake. I have savings so could survive for a little while on no wages. Am I just being impatient and I should just suck it up? Any input into this would be greatly appreciated as I am so tired of all the to'ing and fro'ing in my head.
