all data should be available orally

I just wanted to note that I think it sucks ass that some companies require that their employees show up at work to get their schedules if you call it should not be against company policy for your managers to give you your schedule. I don't personally have to deal with this but if I did I would complain about it allot. I don't drive and spending money to get to work on a day I had off just to get a piece of paper that tells me when i have to come back to work again seems ludicrous. this is in my opinion just another example of stupidity in the corporate world please someone explain how this benefits the companies that enforce this policy and their employees?
