Please submit your timecard at the end of each month, but at the latest by the eighth of the following month. If you need to switch the working shifts on your assigned timecard for some reason, you need to inform me before the end of the month. I will not be expected to make changes after that. For example, April 1-8 is the time frame to submit your March timecard, and any working shifts changes should be corrected before March 31.
