So I've heard. But it does say in our rule book if you are unable to use a computer to duty in (no access in some way) you can call in to duty in. I know people that exclusively call to duty in regardless of computer access. I don't recommend that but really, if you work with them, keep them in the loop, and assure them that everything that needs to happen will happen, they'll work with you.
