HARTFORD — Connecticut lawmakers are considering a bill that would establish labor standards for domestic workers, including nannies and house cleaners. A public hearing is planned on Tuesday before the General Assembly’s Labor and Public Employees Committee on legislation that would create a so-called bill of rights for domestic workers. Advocates said California, Hawaii, and New York have enacted similar laws that provide more legal protections to such workers. There are an estimated 40,000 domestic workers in Connecticut. Advocates say they are excluded from basic protections such as minimum wage and antidiscrimination laws. The Brazilian Immigrant Center said live-in workers are especially vulnerable. Legislation would require employers to advise domestic workers when they are hired about issues such as required hours, compensation rates, and availability of sick time.
