To request leave on the basis of the Family and Medical Leave of Act (FMLA), you must complete the Leave Request Form (FMLA), have it signed by your Principal and submit it to HR. This Leave Request Form (FMLA) should be submitted as soon as you are aware of your need for leave and at least 30 days in advance. (If leave is unforeseen, you MUST submit the form as soon as practically possible.)
