I have recently been lucky to get a job offer and I have been advised that once I will pass the background check I can start working. I wonder about one thing as I didn't put one short-term position on my CV which lasted 1-2 months. I didn't lie on my CV so that short gap of about 2-3 months is visible. I have never been asked any question regarding this.
When I was completing the background check application I did put details of this position so the gap can be explained.
My question is whether my employer can not employ me once he will realize I had a short-term position that I didn't mention? I feel anxious about this check and I don't know whether I should send HR an email now explaining or wait for results?
