I want to send a memo to all employees because many staff are taking their clock cards from the holder and keeping with them. This became problem for admin staff and accounts while preparing salaries- please see the letter below and correct it.- thanks

It has been noticed that many employees are picking up their clock cards from the clock card holder without informing the admin staff. This practice makes both accounts and admin staffs difficulties to find and verify clock cards during the payroll time. Therefore, effective immediately, nobody is allowed to take clock cards from the clock card holder without informing admin staff.
