How do I apply for a Leave of Absence? What date should I use as the start of my leave of absence? When should I apply for FMLA leave? Where do I send the completed leave of absence forms? What type of leave may I use while on a leave of absence? Do I need a doctor’s note to return to work? What if I do not have enough leave to cover my absence? What if I have exhausted my FMLA eligibility but am still sick? What if I need to return to work prior to the approved end date of my leave of absence?
