the official system. Attendance in the early hours of the morning to avoid exposure

assignments that may extend longer than official working hours. There is no
clear system for determining a flexible period of work for field staff, as well
as a lack of a clear mechanism for calculating additional work hours and how to
compensate staff, which has led some staff to prefer field work to field work
and to maintain work efficiency.
