Sick Leave Question: different policy for different shifts!

I can understand the policy from a staffing standpoint, but there have been times that I have awakened feeling ill and would not have had time to call in before the deadline. Conversely do you wake up and know that you are going to be too sick to work at 3am? This is essentially what they are asking nightshifters to do. This is another way that they can encourage people to work sick because now they will be in trouble if they do not know that they are going to wake up sick

If I'm sick enough to stay home from work, I'm usually awake and miserable at 3 AM. Or 3PM as the case may be. There have been a couple of exceptions, but by and large, if I'm that sick, I can't sleep.
