Oregon Tradeswomen


Since 2014, we’ve been collaborating with Oregon Tradeswomen (OTI) to adapt and implement the Green Dot Violence Prevention Strategy that addresses bullying, harassment, hazing, and other forms of aggression in Portland’s construction trades. After an extensive customization of the curriculum, Green Dot for the Trades is currently being piloted on the Multnomah County Courthouse project in Portland, Oregon, led by Hoffman Construction.

The first step in the development of Green Dot for the Trades was engaging in an extensive adaptation process. Our team conducted face-to-face focus groups with a cross-section of stakeholders including foremen, apprentices, women, trades workers of color, and business owners. This process illuminated the unique challenges of working in the trades and charted the way toward ensuring safe and productive work spaces for all.


The next step of implementation was training a group of trades workers from across construction trades to implement the Green Dot Strategy on jobsites. Participants have taken ownership of the program and continue to provide leadership and inspire commitment as they conduct the training workshops.

We are committed to ensuring all programs are evaluated and that outcomes inform course corrections, implementation strategies, and improvements. We worked with OTI to identify an independent evaluator who is assessing our work and informing ongoing efforts.
