More than 100 people — including dozens of dairy workers — rallied outside a Hannaford supermarket and marched through Portland Monday, urging the company to adopt supply chain reforms aimed at protecting farmworkers.

The rally was organized by Migrant Justice, a Vermont-based organization that advocates for farmworker rights.

For years, the group has been asking Hannaford, and other food retailers, to join its Milk with Dignity program, which requires them to pay a premium on dairy products to ensure that workers in the supply chain have adequate housing, paid sick days and other protections.

Migrant Justice leader Enrique Balcazar said the group is focusing on Hannaford because they believe the company would have a big impact on the lives of dairy workers in the region if it signed onto the program, due to its dairy purchasing power.

Over the summer, a group of investors published a letter asking the company to join Milk with Dignity.

Hannaford said it requires all its suppliers to sign a code of conduct assuring that labor laws are “followed stringently” and that workers are treated fairly and humanely.
