California labor laws on sick days protect most workers and require employers to provide paid or unpaid leave for specified health reasons. These rules clarify when you can stay home, how much time you earn, and how to request time off without retaliation.
This guide explains eligibility, accrual rates, caps, and how sick leave interacts with other leave laws, helping both employees and employers navigate compliance in practice.
| Worker Type | Sick Days Accrued | Maximum Carryover | When Usage Begins |
|---|---|---|---|
| Full-time employee | 1 hour per 30 hours worked | 24 hours or 3 days | After 90 days of employment |
| Part-time employee | Prorated by hours worked | Same cap as full-time | After 90 days |
| Seasonal worker | May use yearly cap only | Up to 48 hours | Defined by schedule |
| Union-represented worker | As per collective bargaining agreement | May differ from state law | Per contract terms |
Eligibility and Employer Coverage
Most California employees are covered, including full-time, part-time, temporary, and remote workers. Small businesses with fewer than five employees may have modified rules, while domestic workers and certain farmworkers follow tailored provisions.
Employers must track hours worked to calculate sick day accrual and cannot require a medical certificate for the first three days of each illness, aligning the rules with broader workplace protections.
Small Business Exceptions
Under five employees, an employer can deny paid sick leave until the business reaches a size threshold, provided the worker still accrues time and can use it once the threshold is passed.
Accrual Rates and Usage Rules
Accrual is typically one hour for every 30 hours worked, capped at 24 hours or three days per year unless the policy offers more. Employees can start using sick days after working 90 days, and employers may set a minimum use increment of one hour.
Unused, paid sick time is treated as wages and must be paid out upon separation, ensuring workers keep earned benefits when they change jobs.
Safe Harbor and Good Faith
The safe harbor rule allows employers to cap use at 24 hours if they provide a clear policy and do not deny requests in bad faith. Bad faith includes retaliating against an employee or unreasonably delaying approvals when documentation is complete.
Documentation requirements must be reasonable, such as a signed statement describing the reason for absence, while still protecting privacy and preventing discrimination in how requests are handled.
Enforcement and Worker Rights
The California Labor Commissioner can investigate unpaid sick time claims, and employees may recover wages, penalties, and interest if their employer violates the law. Retaliation claims can be filed with labor authorities, and mediation options are often available to resolve disputes quickly.
- Know your accrual rate and check pay stubs for correct sick time calculations.
- Request time off early and keep a written record of your request and any responses.
- Review your employer’s policy to understand usage rules, caps, and documentation requirements.
- Report unpaid sick time or retaliation to the Labor Commissioner if internal resolution is not possible.
