As with a paper 3971 you will need a signed “Received by” from your manager/supervisor to prove the day you turned in your leave request. After you have an official signature, they have 3 days to respond to you “disapproved” or it is an approved leave request automatically.
Management will back date these forms (illegally) and say that they disapproved them before the 3 days expired. You have to make sure that they know you must be given the disapproval ( in your hand) before 3 days expires. They can verify this by having you sign “Received by date “ somewhere on the slip. Without that they have no proof they returned it to you before 3 days expired.
Please point out to your managers that falsifying this document is punishable by 5 years in prison or $10,000 fine, which is written at the bottom of every 3971.
