First, make clear instructions to security that after the in-time hours, no one will enter the main gate. If they come late (due to some problem), keep a register with the security person to note down the latecomers' names, employee codes, in-time, employee signature, remarks (to note down why they are late), and the signature of the security personnel.
Steps to Ensure Attendance Compliance
Take a class for employees to sign the attendance register in front of security. Based on this attendance register, salaries will be processed; otherwise, no exceptions will be made.
These two steps will be applicable from the top down the hierarchy. This will also help build a good culture in your organization.
