Well,obviously it depends what it is youve done that could get you in bother in the first place.If its not that bad and youre leaving in 15 days then you might as well stay,however if it is something really bad then just pack your bag and go is probably the best bet,and give them some excuse to do wit a new job or something.If you do decide to stay, tell the union and get them behind you just incase anything does get thrown back in your face,at least you have your fellow crew members to back you up,in which case you shouldnt have any problems at all.hope things work out for you
