Welcome to Cook and your new career! Work boots need to have a safety cover over the toes: some folks prefer use steel, some composite. Know that steel will NOT pass the metal detectors, you will have to take them off and run them thru the x-ray, or wear something else in and out of work. There is a national cert - but the official tag escapes me. A lot of the folks wear Redwings, Wolverine, and Caterpillar too - the boot doesn't have to be elaborate - just safe, but that's a different thread. The "Search" function will help you narrow your choices. Scrubs, or modesty garments, don't have to be any color - whatever suits your budget and is comfortable will be fine. Cook is a great place to work as a Jr HP. You will do your time a t control points but also will get meter and survey time too. A positive attitude and energetic work ethic will open lots of doors. G
Give yourself some extra time on your first day. Unbadged workers park across the street in an overflow lot and ride a bus into Training. It's really a sweet deal but will take some time to navigate on the first try. One of the deadly sins here is being late for Training. Good Luck! See you there.
