The federal Family and Medical Leave Act FMLA) and the California Family Rights Act (CFRA) each apply only to employees, spouses, children and parents 2 CCR § 7297.3(e). A cousin is not covered by the Act -- therefore, an employer is not prohibited from terminating an employee who leaves work to care for a cousin.
Note: If the cousin is a "servicemember" (military), then it is possible that the person may be covered under the FMLA -- so, you may want to check with the employee to see if this is the case.
Hope this helps.
