Women make up 3% of plumbers and electricians, and 47% of the women who do enter leave because of harassment — halving an already tiny talent pool

Women represent 2.9% of electricians, 3.0% of HVAC mechanics, and roughly 3.5% of plumbers in the United States — percentages that have barely moved in 40 years despite decades of hiring goals and anti-discrimination laws. This alone represents an enormous untapped labor pool in an industry short over 500,000 workers. But the problem is worse than the entry numbers suggest: of the women who do enter the trades, 47% leave or want to leave specifically because of harassment or lack of respect on the job. Nearly 1 in 4 tradeswomen report experiencing frequent or constant sexual harassment. The retention failure is where the real damage compounds. It costs an employer $10,000-$20,000 to recruit and train a new apprentice. When a female apprentice completes two years of a four-year program and then quits because of a hostile work environment, that's a dead loss — for the employer, for the apprenticeship program's completion statistics, and for the industry's labor supply. Multiply that by thousands of women across the country, and you get a meaningful fraction of the labor shortage that is entirely self-inflicted. The downstream effects hit everyone. Homeowners face longer wait times and higher prices because the industry has effectively locked out half the population from entering it. Contractors who do employ women often lose them to competitors or other industries, wasting their training investment. And the women themselves — who chose the trades because they wanted hands-on, well-paying careers without college debt — are forced out of an industry they wanted to be in. The structural reason this persists is that jobsite culture is set by crews, not by HR departments. Most tradespeople work for small companies (under 20 employees) that have no HR function, no harassment training, and no formal complaint process. The foreman is often both the most experienced tradesperson and the source of the hostile behavior. Reporting harassment means reporting your direct supervisor to an owner who is likely his friend. Union grievance processes exist but are slow and can result in the complainant being blacklisted from future job assignments. The number of women apprentices has doubled between 2014 and 2022, reaching 14% of active apprenticeships, but the pipeline leaks faster than it fills.
