What does a typical day look like for a Union Construction Flagger on a jobsite?

A typical day for a Union Construction Flagger involves arriving on site before construction begins, setting up warning signs and safety cones, and coordinating with the crew supervisor to understand the day’s work zones. Throughout the shift, you’ll direct vehicle and pedestrian traffic using signs, hand signals, and occasionally radios to ensure a safe environment for both workers and the public. Flaggers often work in outdoor conditions, sometimes in extreme weather, and must stay vigilant for long periods.
