Meet Our Team
Mike Black
President & Steward
Mike became active in the Union in early 2020 as he recognized how economic justice ties in with the broader push for social justice – and the powerful role unions can play in support of the cause. Prior to working for the Peace Corps, he served as a Community Economic Development Volunteer in Albania from 2017-2019, where he undertook a diverse range of activities in his community. While he misses Albania’s snow-topped mountains and ubiquitous invitations to coffee, he appreciates playing a role in inspiring the next generation of Peace Corps volunteers as the Regional Recruiter in his hometown of Boston. |
