Claimants approved for intermittent FAMLI leave shall submit requests for benefits within 5 business days of leave being taken unless good cause can be shown. Intermittent FAMLI leave shall not be taken for less than 4 hours unless the claimant’s scheduled shift was fewer than 4 hours. Benefits will not be issued for requests that significantly exceed the expected duration and frequency listed on the medical certification without an updated certification. Approved intermittent leave applications expire after one year. If a claimant requires additional FAMLI leave for the qualifying event subject to the expiration period identified in §D of this regulation, the employee will have to submit a new claim application.
