On a ship: Working during the time between the point you started to fake you are injured (or sick) and the time you can get your actual medical advice to leave the vessel. You have to be present and work as much as you can, but you need to stress out that you can not work up to 100% and you need to moan and look miserable whenever someone sees you.
- Hey Babbaloo, I heard you have an accident on the stairs. What the fuck are you doing here?
- Oh, I'm just ghosting in the Laundry till we get to Wienna and I can go on sick leave.
