I have a job offer and I'm just waiting for the contract. I'm still in probation for my current job which means my notice is only a week.
I am pretty junior at work so don't want to give the impression that I'm indispensable or something. However, I know me leaving will have repercussions.
Basically I was trained on a new procedure with the intention that I would then go on to train my colleagues on the procedure. As it stands so far I have only trained one other person (out of my control, they haven't been able to spare the staff to give them time to train as we are short-staffed). The procedure is supposed to be ramping up soon and the intention is that between me and the person I have trained and our supervisor/manager it will be enough people which is already short-staffed (we really need to be in a team of 4 rather than 3).
When I give my notice it will just be that one person who I have trained. They have only been trained on half of the procedure due to factors outside of my control (too complicated to explain). My manager does not know the procedure fully, he only knows the parts he is responsible for rather than the parts I do.
I feel guilty and know upper-management will be frustrated and won't expect this. I kind of want to let my manager know in advance that I'll be leaving soon, or I have thought about whether to ask my new job for a delayed start date (not long, just maybe 4 weeks) to give me chance to train some more people. I have asked to train more people without mentioning why but they don't have the people to spare...
What do you think?
