Glaziers held about 41,900 jobs in 2010, of which 62% were employed in the foundation, structure, and building exterior contractors industry. Another 15% were employed in the building material and supplies dealers industry. About 5% of glaziers were self-employed.

As in many other construction trades, the work is physically demanding. Glaziers spend most of the day standing, bending, or stretching, and workers often have to lift and maneuver heavy, cumbersome materials, such as large glass plates.

Glaziers experience one of the highest rates of injuries and illnesses. Typical injuries include cuts from tools and glass, and falls from ladders and scaffolding. Most glaziers work full time.
