The measure known as the grand bargain bill will be signed by Governor Charlie Baker today.
The governor is holding a signing ceremony for the bill, which raises the state minimum wage to 15-dollars an hour by 2023.
It will also allow nearly all employees in the state to take up to 12 weeks of paid family leave starting in 2021.
The paid family leave will cost 800-million-dollars a year, and will be funded through a payroll tax on state workers and employers.
The bill will allow for a permanent state sales tax holiday in August something that western Mass lawmakers had been wanting for years.
