A DAY IN THE LIFE OF AN ENTRY-LEVEL DAY OR NIGHT TRUCK UNLOADER

As a Truck Unloader, you are the cornerstone of our production process. You ensure that our raw floor has enough raw material to run the manufacturing plant. Based on what is available and what is needed, you communicate effectively with the Raw Loader Operator to coordinate which loads should be dumped next. You keep a running log of the trailers dumped as well as what is available in the yard. Much of your time is spent jockeying trailers and tipping them with a truck tipper. You work in a safe and timely manner.

You ensure a steady flow of raw material in order to maintain a consistent mix of materials. To make sure that the trailer is set up in accordance with customer requirements, you clean the Yard truck and dock area after dumping. You position each trailer in the holding lot to ensure readiness for the next routes. As a get-it-done person who likes to be active, you take pride in a job well done!


MINIMUM QUALIFICATIONS FOR AN ENTRY-LEVEL DAY OR NIGHT TRUCK UNLOADER

  • Must be at least 18 years of age.
  • Ability and willingness to work safely outside in the weather.
  • Manufacturing, industrial, or agricultural experience is preferred.

PREFERRED QUALIFICATIONS include:

  • Ability to accurately fill out paperwork for loads dumped.
  • Ability to handle, move and lift up to 50 lbs.
  • Basic math skills.

Manufacturing, industrial, or agricultural experience and Yard tractor experience are helpful, but multiple factors will be taken into consideration. Do you have good communication skills, both written and verbal? Are you attentive to safety? Do you have a strong work ethic? Are you self-motivated? If so, you might just be perfect for this entry-level job as a yard jockey!

DAY OR NIGHT WORK SCHEDULE

The full-time yard jockey job works either 10-hour nights on Mon-Sat. This production plant operates 24/7 and the flexibility to work days, nights, or weekends as needed is required.
