Understanding Employee Resignation Amidst Fraud Allegations
From your statement, it is understood that three employees were said to be involved in fraud, which could not be attributed to any particular person among these three. Further, you mentioned that one of the above three has already left your company. How did he leave? Did he tender his resignation after receiving a show-cause notice? If so, why did management accept his resignation when the show-cause notice was pending? Or has he gone on unauthorized absence from duty upon receipt of your show-cause notice?
If the person who left your company is absent from duty, we have to doubt his integrity and accordingly, we need to take disciplinary action against him on the grounds of not only fraud/financial loss to the company but also unauthorized absence from duty. However, you mentioned that you gave notices to all three employees and out of that, one left. The remaining two claim they are innocent and that the third person who left the service is guilty.
Steps to Address the Situation
To get the facts of the case, you need to issue a charge sheet by framing relevant charges to all three, including the person who stays away from duty. Upon receipt of an explanation from these three, you need to conduct an inquiry if necessary to establish the charge. The inquiry officer can decide who is guilty of misconduct and accordingly, you can award punishment to the person or persons responsible for committing fraud.
Without following the procedure, you cannot establish the charge against any of the above three employees. Furthermore, you mentioned that management does not want to lose the services of the other two employees due to a shortage of manpower. This indicates that your management is having a dual stance regarding employees alleged to have committed financial irregularities. If manpower is short, then they might take a lenient view on any employee who commits misconduct and fraud in connection with company business. Does this not lead to further indiscipline among other employees in your organization? If the management's stance is like this, why have they issued show-cause notices to the three employees under reference?
I strongly suggest that the person who is said to have committed financial irregularity should not be kept in the services of the company any longer, which may prove detrimental to the interests of the company in the long run. This is my advice, and let us have an expert opinion from our learned members.
