Glazier
Glazing work resists automation because glass installation requires human judgment, precision, and adaptability in unpredictable construction environments.
In real usage data, AI shows up in this job less often than in most occupations.
Technical detail
Based on Microsoft's "Working with AI" study of real Copilot conversations mapped to O*NET tasks (arXiv 2507.07935): Glaziers scored 0.053 on AI applicability, notably below the cross-occupation mean (0.159, stdev 0.098) across all 785 SOC codes studied — banded here as Low real-world AI usage relative to other occupations.
What a glazier actually does
Glaziers install glass in windows, skylights, storefronts, curtain walls, and display cases. The work involves reading blueprints and specifications, measuring and cutting glass to fit openings, preparing frames and applying weatherproofing, using suction cups and mechanical glass lifts to position panels that can weigh hundreds of pounds, securing glass with clips, gaskets, and structural silicone sealants, and installing mirrors, glass railings, and decorative glass elements.
Modern glazing work increasingly involves specialized products, including tempered safety glass, insulated units for energy efficiency, laminated glass for security and sound control, and low-iron or decorative glass for architectural effect. Commercial glaziers work on curtain wall systems that form the exterior enclosures of modern buildings, requiring precision installation of complex aluminum framing and glass panel systems, often from swing stages or scaffolding many stories up.
Residential and commercial interior glaziers replace windows and install shower enclosures, glass partitions, and storefront entrances. The job demands physical strength for handling heavy glass, precision for cutting and fitting, and constant attention to safety when working with a material that can cause serious injury. Most glaziers learn the trade through a multi-year apprenticeship combining paid on-the-job training with related classroom instruction.
Why it reads this way
Glazing work resists automation because glass installation requires human judgment, precision, and adaptability in unpredictable construction environments. Every opening is slightly different from specifications; frames may be out of square, dimensions may vary from blueprints, and existing conditions require assessment and adaptation. Handling glass requires continuous judgment about balance, grip, and positioning—a moment's inattention can shatter expensive panels or cause serious injury.
Glaziers must assess whether openings are ready to receive glass, make real-time decisions about shimming and adjustment, and verify waterproof sealing that prevents costly future leaks. High-rise curtain wall installation involves working at heights in wind conditions that affect how glass can be safely maneuvered. The variety of glass types, framing systems, and installation conditions means each project presents unique challenges. Customer interaction is significant in residential work—understanding homeowner preferences, recommending appropriate products, and explaining options requires human communication.

Head-to-head comparisons
Glazier (structuralScore 91, Safe band) clears the robotics check as of August 2026. Curtain-wall installation robots (cable-driven parallel robots studied under the EU HEPHAESTUS/BERTIM research programs) exist but remain single-site academic proof-of-concept systems, not commercial products in active use. Only Connecticut and Florida require an individual glazier license; most other states license only the glazing contractor's business, which carries the same qualifying-individual leakage risk documented for general contractors, so this is disclosed as a partial, not clean, legal wall. O*NET confirms strong physical-precision and weather-exposure demands. Medium confidence reflects that the licensing wall is nominal in most states and several market-size claims found were excluded as low-quality aggregator sources.
This is a researched judgment (checklist v1.2), not a statistical measurement — it sits alongside, not instead of, the structural exposure signal above. Next scheduled review: 2027-08-10.
