Construction workers are an essential part of the building industry. They come in a variety of roles, such as erecters, masons, tilers, and hardhats. Erecters are responsible for assembling and erecting structures, such as buildings, bridges, and towers. Masons are skilled craftsmen who build structures out of stone, brick, and concrete. Tilers are responsible for laying tiles on walls and floors. Hardhats are workers who wear protective headgear to protect themselves from falling objects and other hazards. All of these construction workers play an important role in the construction industry.
