The bill amends Chapter 151B of the General Laws to enhance workplace training and policies against sexual harassment. It mandates that all employers, employment agencies, and labor organizations create and adopt a comprehensive policy against unlawful harassment, including sexual harassment. This policy must include a clear statement of the unacceptability of such behavior, a description of the complaint process, and the consequences for violators. Employers are required to provide all employees with a written copy of this policy by January 1, 2027, and to ensure that training on preventing unlawful harassment is conducted within six months of hiring or promoting an employee.

Additionally, the bill specifies that training must meet certain minimum standards, including being interactive, lasting at least one hour annually, and including bystander intervention training. Employers must maintain records of employee training for a minimum of five years and provide these records to the Attorney General or the Massachusetts Commission Against Discrimination upon request. Notably, the bill exempts employers with 25 or fewer employees from certain requirements, but they are still encouraged to promote a harassment-free workplace. The Attorney General is also granted the authority to establish necessary regulations to implement these provisions.
