Dear Shafaq, please make policies that are not one-sided. Do not insist on bonds from employees; these are not valid in law and will only create tension. Leave the employee free to quit, but do try to retain them with good and fair policies. Give them encouragement. No employee wants to leave if they receive reasonable pay, perks, and a good environment in the office. It is not possible to abolish favoritism, but make an honest effort.
All the best.
I was affected by the bond and had to fight to get out of it. Many are not that lucky.
Goodbye,
Sekar.
