Pay starts day one of Indoc. You will be on the 18 day schedule and pay until a schedule bid is released. You can bid any one of the three. Your seniority will demermine if you get the one you want. This varies between fleets. If you want the 18day and your seniority flushes you out, you will be put on 7&7. Most likely you will go home in between Indoc and Initial type.
