If a user shows a history of overdue return dates, then Overtime protection can be activated by an xChange admin. This doubles the per diem for the user to increase the speed of which they return units. Overtime protection doubles the per diems after 30 days of per diems have been paid.
Example: Company A has a history of overdue return dates. Company A uses containers from Company B with 60 freedays with a per diem of $1. After 60 free days Company A starts paying per diems. The containers are not returned within the first 30 days of paying per diems. The per diem is now doubled to $2.
