The jarring message — “White Power” — was scrawled in fire-engine-red marker in one of the busiest spots at Massachusetts Eye and Ear hospital, near an elevator that hundreds of patients, visitors, and workers pass every day.

Emotions were already raw in the days following the presidential election, and the graffiti, discovered Nov. 18, was a “big slap in the face,” said Dr. Rebecca Hammon, a resident at the Boston teaching hospital, which employs many people of color.

While the incident was a first at the hospital, such workplace events nationally grew increasingly common over the course of last year’s presidential campaign.

And that was before millions of people across the country took to the streets in recent weeks to protest and many businesses closed in a nationwide action called a “Day Without Immigrants,” designed to illustrate the effect immigrants have on the US economy.

With future workplace strikes planned — a national “Day Without A Woman” action is slated for early March — employers are seeking guidance about how to respond, Blagg said.
