That's with a break between. For example, if you started your trip at a home terminal and went down to a turnaround point and, say, you got there in seven or eight hours, you would be able to come back after taking a bit of a break at that destination point. However, if the employee felt tired or thought it would be an unsafe thing to return, then they have the option of booking rest there, away from their home terminal.
