A new study shows that more than in any recent year, labor-affiliated shareholder activism in 2014 has primarily involved public employee pension funds, especially those for New York City and state, as well as the American Federation of State, County and Municipal Employees (AFSCME), a major union that represents mostly public-sector workers.

“The New York State fund and the AFSCME fund have been almost single-mindedly focusing their 2014 shareholder-proposal activism on corporations’ political spending, principally targeting Republican-favoring companies,” according to the study, titled “Special Report: Labor-Affiliated Shareholder Activism.”
