Connecticut PTO Laws: Sick Leave, Accrual, and Carryover

Connecticut PTO laws require most private-sector employers to provide up to 40 hours of paid sick leave per year, accrued at one hour for every 30 hours worked.¹ The state does not require employers to offer vacation time, personal days, or a combined PTO bank. Those benefits exist only if the employer chooses to offer them, and they are governed by the employer’s own written policy rather than by statute.

The paid sick leave mandate expanded significantly in 2025, replacing an older law that covered only certain “service workers” at large employers. The new version phases in by employer size, and as of January 1, 2026 it applies to any employer with 11 or more employees in Connecticut.²

Which Employers Have to Provide Paid Sick Leave

Coverage phases in over three years based on workforce size:

25 or more employees: covered since January 1, 2025
11 or more employees: covered since January 1, 2026
Any number of employees: covered starting January 1, 2027

Employer size is measured each year based on the payroll for the week containing January 1.³ The old law covered only employers with 50 or more employees and only hourly service workers in specific occupations like food service, retail, and healthcare. That narrow scope is gone. The current law covers nearly all private-sector employees regardless of occupation or pay structure.

Two groups remain excluded: seasonal employees who work 120 days or fewer per year, and certain construction workers at exempted employers. Day laborers and temporary workers, previously carved out, are now covered.²

How Sick Leave Accrues and When You Can Use It

Covered employees earn one hour of paid sick leave for every 30 hours worked, up to 40 hours per year.¹ That is faster than the old rate of one hour per 40 worked. Accrual starts on the first day of work, but a new hire cannot use the leave until the 120th calendar day of employment.⁴

Instead of tracking accrual hour by hour, an employer can front-load the full 40 hours at the beginning of the benefit year. Front-loading satisfies the law as long as the employee gets at least 40 hours available for immediate use, and it eliminates the need to monitor individual accrual balances.⁴

What Paid Sick Leave Can Be Used For

The permitted uses go well beyond a simple sick day. Employees can use paid sick leave for any of these reasons:⁵

An illness, injury, health condition, medical appointment, or preventive care for the employee’s own physical or mental health
The same health-related reasons for a family member. Family member includes a spouse, sibling, child, parent, grandparent, grandchild, or someone related by blood or close association equivalent to those relationships³
A mental health wellness day, with no diagnosis or medical appointment needed
A public health emergency when a public official orders the workplace or a family member’s school or care facility closed
Exposure to a communicable disease when the employee or a family member poses a risk to others
Time off related to being a victim of family violence or sexual assault, including medical care, counseling, relocation, or legal proceedings

Under the old law, leave was limited to the employee’s own illness, medical care, or caregiving for a spouse or child. The 2025 expansion broadened the family violence and communicable disease provisions and added the mental health wellness day.²

Notice and Documentation Rules

This is where the current law diverges sharply from what many employers still expect. The statute does not require employees to give advance notice before using paid sick leave. Employees should notify their employer as soon as practicable when calling out, but employers should not discipline workers for failing to follow internal call-out procedures.⁴

Employers also cannot require a doctor’s note or any other documentation to support a paid sick leave request. An employer may ask whether an employee is using paid sick leave, but cannot demand specifics or proof for any absence within the 40-hour annual entitlement.⁴

Carryover and the Annual Cap

Employees can carry over up to 40 hours of unused accrued sick leave from one benefit year to the next.² Even with carryover, an employer is not required to let an employee use more than 40 hours in any single benefit year.⁴ The carryover rule protects employees who accrue hours late in the year and would otherwise lose them.

Employers that front-load the full 40 hours at the start of the benefit year can skip carryover tracking entirely. As long as at least 40 usable hours appear on day one of the new year, front-loading satisfies the carryover obligation.

Vacation, Personal Days, and General PTO

Connecticut’s paid leave statute governs only sick leave. It does not require employers to offer vacation time, personal days, or a combined PTO bank. When an employer chooses to offer any of these benefits, the terms come from the employer’s own written policy or employment contract.

Connecticut does not treat unused vacation time as earned wages that must be paid out at termination. Whether a departing employee receives a payout for unused vacation or PTO depends entirely on what the employer’s policy promises. If the policy says unused vacation is forfeited at separation, that is enforceable. If it promises a payout, the employer must honor it. An employee whose employer refuses to pay out vacation guaranteed by policy can file a wage complaint with the Connecticut Department of Labor or pursue the amount through the courts.

Employers that bundle sick leave into a broader PTO bank still have to make sure employees can use at least 40 hours of that bank for every purpose the sick leave law allows. Labeling something “PTO” does not eliminate the statutory sick leave obligation.

Recordkeeping and Workplace Posting

Employers must track hours worked and paid sick leave accrued and used for every employee, as part of standard payroll records.⁴ The Connecticut Department of Labor can inspect these records at any time.

Employers must also post a workplace notice explaining paid sick leave rights. The Department of Labor provides a prototype notice in English and Spanish that must be displayed once the employer becomes covered. For employers newly covered as of January 2026, the notice obligation begins immediately.⁴

Retaliation Is Prohibited

Employers cannot fire, demote, suspend, or otherwise punish an employee for using paid sick leave, requesting it, or filing a complaint about a violation. Cooperating with a Department of Labor investigation or testifying in a related proceeding is also protected.⁶ Counting paid sick leave absences under a “no-fault” attendance policy is the most common way employers trip over this rule, and it is a clear violation.

Retaliation carries a civil penalty of $500 per violation. The Department of Labor can also order the employer to reinstate the worker, pay back wages, and restore any lost benefits.⁶

Filing a Complaint and Penalties

The Connecticut Department of Labor investigates complaints and enforces the paid sick leave law. Any employee who believes their rights have been violated can file a complaint, which triggers an investigation and potentially a hearing before the Labor Commissioner.

Penalties depend on the violation. Retaliation carries a $500 civil penalty per violation. Other violations, such as failing to allow accrual, improperly denying leave, or not maintaining required records, carry penalties of up to $100 per violation.⁶ Beyond fines, the Labor Commissioner can order reinstatement, back wages, and restoration of lost benefits. Either party can appeal the Commissioner’s decision to Connecticut Superior Court.
