You can take paid sick leave for yourself or a family member, for preventive care or diagnosis, care or treatment of an existing health condition, or for specified purposes if you are a victim of domestic violence, sexual assault or stalking.
Family members include the employee’s parent, child, spouse, registered domestic partner, grandparent, grandchild, and sibling.
Preventive care would include annual physicals or flu shots.
The employee may decide how much paid sick leave he or she wants to use (for example, whether you want to take an entire day, or only part of a day). Your employer can require you to take a minimum of at least two hours of paid sick leave at a time, but otherwise the determination of how much time is needed is left to the employee.
