Here's a Quick Tip when someone is on vacation or will be off work for some extended period of time. If they know in advance, they can set themself to UNAVAILABLE.
However, if they forgot to change their status, and you think you are Dispatching them to a Dispatch, only to discover that you are not, use the "RESOURCES" link available from the Main Dispatch View screen. This will take you to the View Resources page.
Click ALL from the Menu to display ALL Resources and ALL Areas.
If the Resource name is in BOLD TYPE, they are available to Dispatch. If someone is not on site or will be out, clicking on that Resource will un-bold their name, showing that they are Unavailable to Dispatch. This will save a lot of time and frustration when folks are off work.
