Aaron and I forgot to mention that you do not have to be in the library to look at the staff exchange. You can read or post to the exchange from home. Why would you?
1. We could post emergency closings on the staff exchange. We would still try to call everyone, but that takes time and we sometimes do not reach everyone for one reason or another. If there is bad weather and you are uncertain whether to come to work, you could get your answer from the staff exchange. This is an idea that does not yet have procedures instituted.
2. You remember something you forgot to do at work and it is too late to call someone. Posting on to the staff exchange would give others a chance to help you out.
3. You just heard a great book review on the radio and you want to give us an alert.
These are just some ideas. Can you think of others?
