Baseline characteristics by cohort

Baseline characteristics by cohort
Measure	Mentees n=51 Participants This arm consists of apprentice-level, female-identifying construction workers who will receive active mentorship (the intervention) for two years from trained journey-level mentors. Mentoring program: Apprentice-level female construction workers will be assigned to a mentor who has gone through a rigorous mentorship training. Participants will be asked to meet with a mentor at least 4 times/year in person to discuss the challenges of being a female in construction, learn coping mechanisms, and otherwise discuss the unique challenges of the job environment.
