Paid Family Leave

Employers with at least one employee in the state can offer the state-run Connecticut Paid Leave program or choose to opt out and purchase a private plan to offer all employees.

Employee contributions (a percentage of earnings up to the social security contribution limit) fund the program.
Employers must provide 12 weeks of paid leave and potentially more for eligible employees with a qualifying experience.

Employers opting out of the state plan must apply and receive approval from the CT Paid Leave Authority to use a private plan.
A private plan must provide the same or better benefits than the state program.
