As long as I show a class schedule with my name on it, it doesn't matter how many classes they have to sign the loa paper right? and it could be as long as I say it is (4 months) in this case right?
From experience from my team members taking loa they just said they needed it, filled paperwork and it got aproved. It might be just our store thats leanient so I'm not sure what best practice is.
