From his official bio:
In 1997, he was elected to serve as a State Representative for one of the most diverse districts in Massachusetts. There, he focused on creating good jobs, protecting workers’ rights, expanding mental health treatment, and investing in public transit.
Following his time as a State Representative, Secretary Walsh spent the last seven years as the Mayor of the City of Boston. While mayor, he led the creation of close to 140,000 jobs and helped secure a statewide $15/hour minimum wage, paid sick leave, and paid parental leave. He established Universal, high-quality Pre-Kindergarten for all children, and free community college for low-income students.
He seems like exactly the type of guy who would run a department that would frown upon a man refusing to pay another man what he is owed as his employee.
