Hi,
You consider the particular person as a valuable employee and tried and retained him. If u cut his salry for this 2 days , that may be enough reason for himto reconsider his decision and it will finally prove as bad for you.
If u dont pay for those days ,he will be losing that money because he revoked his earlier decision listening to ur words.
This is what from the employee's perspective. You can either ignore as he had not submitted the resignation and hence there is no question of deducting the salary or u can consider those days as leave , incase still u cant consider so.
But anyway if u deduct the salary for those 2 days, it will go against you, ultimately.
