"The new law creates significant traps for unwary employers. In addition to prohibiting employers from retaliating against employees for requesting, taking, or inquiring about sick leave, the law prohibits employers from denying or interfering with legitimate sick leave requests. Employers also are prohibited from conditioning sick leave approval on employees finding replacement workers or working alternate shift to make up for time missed. Further, the law mandates that employers may require [documentation only] for sick leave absences lasting three days or more. Finally, covered employers will be required to post a notice describing the new law."
