Concrete Workers mix, pour and finish concrete for a variety of different construction jobs. This is a position that revolves around manual labor, so it is not a position for people who prefer to work at a desk. Concrete Workers often work outside or inside unfinished buildings, so they have to work in both the hot and cold weather. This is a position for those who have manual dexterity and average physical strength, as it involves using tools and lifting bags of concrete mix. As mentioned above, Concrete Workers are employed by the construction industry. The construction projects they work on include new building construction, sidewalks, parking lots and driveways. They usually work 40-hour workweeks and during the day, although evening and night projects are a possibility.
