I need your advice guys:
Now there's only 2 of us in a team of what should be 4 people. I'm the high performer of the 2 of us. Significantly.
I have the most difficult clients and have the most responsibility.
Next Thursday my probation ends.
I am underpaid 25-30k compared to the same role elsewhere.
Should I attempt a negotiation of salary?
I'm crowd sourcing opinions. I've never done this before. I'm in a really strong position as I will no doubt be training any new staff, and will get the most difficult client of the guy who just quit.
