Before you bid on an Op, please consult your schedule and means of transportation closely to ensure that you can make it to the Op. Withdrawing your bid within 12 hours will negatively affect your reliability rating.
Make sure to check the Op description so you can see if there are any dress codes or PPE requirements. Showing up unprepared or not performing to your full abilities can cause you to be disputed. Disputes will negatively affect your reliability rating.
