One of my lads is on a ship at present and seems to regularly work a lot of hours. Over and above the normal working day and duties, he'll often work till late at night. Not for any emergency, just part of his workload. He's not always asked to do this and is not dripping, it just comes up in conversation - there's work to be done and he does it. I was wondering, would this be branch or part of ship specific or is it par for the course across all departments in today's Navy and are ships possibly somewhat undermanned?
