Basically, they want everyone to have their official job so the ship gets to Midway quicker. It's going to be a post in the middle of the month that has the heads, and everyone signs up. We'll link this on the main post. The barracks will have all the other jobs like normal listed.

No, not all official jobs are being changed. If your character has an official job, you'd just sign them up for it again and they'll keep it bc they've done it so long already. Every job will fall under a category, you can pick which one you think is closest.

The new head doesn't pick. The mods oocly decide. The heads just get to help crew if they want to find a new job. Rinzler could keep his job if you wanted him to. Same with the workshift coordinator, that could be listed under Navigation and he would still work with all the departments. It's really not as strict as all that. They just want to help get everyone working.
