I've seen this on several applications and it worries me a bit!
I do have perfectly good referees, but two of them are my current line manager/operations manager and I worry that they'll lose confidence in me once they find I'm seeking another job.
I actually love my current job but need more money and at risk of sounding like a cliche, I want to find something where I can progress further - and sadly my current place isnt in a position to offer me either at the moment whereas other places do.
Do they actually check them prior to interview? And if so, does anyone know why?
