The bill amends Section 25-3-1 of the General Laws in Chapter 25-3, which pertains to work on holidays and Sundays. It introduces new definitions, including "employee" and "employer," with significant changes to the criteria for each. The definition of "employee" now includes individuals employed by a municipality or the state and those covered by a collective bargaining agreement or employment contract. The term "employer" is redefined to apply to any entity that employs fifteen (15) or more employees, replacing the previous definition that included any employer with one or more employees.

Additionally, the bill removes specific exclusions for employees engaged in telephonic customer service and related operations, which were previously not considered employees under this law. The list of recognized holidays is also updated to include Dr. Martin Luther King, Jr.'s Birthday for state and municipal government offices. The act is set to take effect upon passage, reflecting a shift in labor definitions and potentially impacting labor practices in the state.
