there are many objections as well as exceptions also to make a remedy, but without the details of actual situation, or the cause of using the hotel payment, its not worthy to make any comment.
It is suggested that you issue a charge sheet and conduct an enquiry. Thereafter, depending on the actual need of that employee as well as judging the gravity of action, decide the quantum of punishment.
He has produced bills very much lower than this Rs. 1200 per day.
If the bills are from the hotel, Finance Deptt. has no right to ask for resignation or termination.
Finance Deptt. can only ACCEPT or REJECT a bill. That's all.
They should not concern themselves with employee discipline. It is the area of HR Deptt or Line authorities.
But I think nothing constructive can be expected from family owned and family run companies. They are not run in a professional manner, nut as a proprietorship concerns.
His entitlement towards lodging per day might be Rs.2000-00 or the actual bill whichever is less. Therefore, he might have inflated the actual expense incurred in this behalf under the belief that it would not arouse any suspecion for it is less than his entitlement. Had the hotel issued the bill for the amount he claimed, it may be technically correct. But, as per your last post he is alleged to have corrected the bill, not only on this ocassion but before also. Therefore it is a fraudulent claim supported by bogus or fabricated bill.
If it is clear case of fraud, have one-to-one talk with him. Make him aware that company will conduct enquiry and will terminate service. This will be setback to her / him. So ask for resignation. If this is done, immediately issue relieving letter. Don't condone fraud even of 'good employee' as it may cause serious difficulties.
