Work Environment

Work takes place in an open garage environment set in a gravel yard, with much of the work performed in a shaded but hot outdoor area. The setting is a heavy industrial, ready-mix and aggregates operation with dusty, noisy conditions and frequent interaction with heavy machinery and mobile equipment. Training typically runs for about two weeks on a 6:00 a.m. to 6:00 p.m. schedule, Monday through Saturday, after which you transition to an overnight-focused schedule aligned with driver activity and production needs. Typical workdays start around 6:00 a.m. and run until the work is finished, which may be a 12-hour shift, with overnight work required and 50–60 hours per week common. You may work across multiple plant locations within the region, including larger high-volume facilities and smaller satellite plants, and may occasionally assist on overnight projects at different sites. The role requires working on catwalks and at heights of 60–80 feet, as well as in confined spaces around heavy trucks, loaders, forklifts, and industrial support equipment. A valid driver’s license is required to move vehicles and equipment as needed, and security-controlled access may be in place at certain plant locations. Appropriate workwear, including steel-toe footwear, is expected, with support provided for safety footwear once permanent.
