One candidate is there for whom we got a call for third-party verification from some other company and who is still our employee and didn't submit a resignation. He/she told us that because of a huge family issue, he/she is not able to come to the office for the last 15 days. Now another problem is we shared his/her profile with clients, and from there, we found out that his/her 2 years of experience is fake. This is an escalation for us. What action can we take for this kind of candidate? Please help me out.
