BOSTON (AP) — State lawmakers are calling on corporations in Massachusetts to add more women to their governing boards.

The Senate has approved a non-binding resolution that encourages publicly-traded and privately-held companies to improve gender diversity on boards and among top management.

According to the resolution, women made up 48 percent of the state’s labor force in 2014 but held less than 15 percent of corporate director seats and less than 12 percent of executive officer posts among the state’s 100 largest public companies.

The measure sponsored by Sen. Karen Spilka of Ashland and Rep. Patricia Haddad of Somerset sets goals for corporations with nine or more directors to have at least three women on their boards by the end of 2018, and firms with smaller boards to have at least two female directors.
