FMLA allows employees to go on leave for up to 12 work weeks in a year. This leave is unpaid but you are able to keep your health benefits during this time. You will also be able to return to your job, or an equivalent job, after your leave is over.
Is this something you've done? (Or considered doing?) If so, what factored into your decision? What was the process like? Do you have any advice for others who may be considering this as an option?
