i would like to inform you that I will not allow you to get approval from your supervisor about forgetting to clock in/out ,It will be start from next month(June). If you for get to clock in/out It means that you will not get money for that day.
You have no excuse because I have already informed you in this email.
Moreover,you need to record the time you clock in/out everyday because there is no record in this application.
So it is your responsibility to note the time.
