You sound like you are in section 2 at MARF. That has to be the laziest, most disgruntled group of EMs ever. So you joined the navy and don't want to work? Well, sorry, you are going to have to... and you get to go to sea too. And getting out of subs... that can be a challenge but it can be done. But it is all needs of the Navy. Like LDO said... you need to escalate your desires up your chain quickly. Your staff adviser, unless he is a good one, probably isn't going to do anything about it. As for work load for EMs on subs, I don't know where you get your info, but its not that bad. You must be listening to some guys that are just really disgruntled, which it seems most EMs at prototype are for some reason (hence the section 2 reference). The only thing that probably sucks about it is having to fix the cooks equipment when it breaks... and it can break pretty frequently. However, sub EMs tend to have the most free time in port. A well run division has all of their work done underway. Anyway, good luck with your "predicament."

PS When you get to you boat, I want you to go tell M div that you have more work than they do. And, sub pay has always been paid back to original enlistment.
