CDN Aviator is right,
OT is not a right, it's a privilege. Think about this for a second. In any other job you pay to get trained in a school, then you apply for a position and get hired if your resume is the best that they have to chose from. If you made the wrong choice, tough luck. You can return to school or do your job and hope you will like it some day.
In the military it's different. You get to choose for the trade you want. Of course we have different openings like any other businesses. Maybe you want a certain job, maybe we don't need it. This is where the problem occurs. Some people think they can beat the system here. Now realise that the military will send you on basic training, then if you need some language training, they will take care of that. After that you go on your QL3 (basic MOC qualification). Because we are trying to train many people, the system is over loaded, no problem, you still get paid to wait for your training. Realise this people, you are useless the military until you are at lease QL3 qualify, for officer I'm not sure of the training, but I think it's a bit longer. Anyway...
Normally they would hire you after you have a qualification, but because of the nature of our job, they have to train you if they want people. So after you reach that point they spent maybe over 300 000$ on you. It's just a guest, I don't know the real figures, maybe someone can fill in here. A bit over a year salary, clothing, paying instructors, overhead expenses, security checks...
So if you re-muster, it means they have to find another person to do the job, train them again.... When they hired you it's because your position was already missing somewhere. So let's say you are a NESOP (my trade), you get trained and get a re-muster after your training. It means that the guy we are missing on the ship will not show up as predicted and it's going to take maybe another 2 years before we can get it.
Now, please pick the right trade and stick with it..
