Final answer:
Managers are expected to monitor and adjust the head count before shifts by making DOP adjustments, ensuring adequate staffing levels.
Step-by-step explanation:
The subject of the question pertains to the responsibilities of managers before the start of a shift in a business setting. Specifically, managers are expected to take stock of the number of employees scheduled for the shift (head count) and adjust the Duty of Position (DOP) accordingly.
Being prepared for one's first day of work involves checking job offers for instructions, knowing start times, and understanding the protocol for reporting time off. Regular and punctual attendance is expected, and showing up on time for designated shifts is a must unless there are valid reasons for absence. It is not specified in the question what is meant by 'uploading this', but it can be assumed that there is a digital system in place for managing the headcount adjustments.
