I disabled the IM app we are supposed to use, "on accident". Somehow I have never gotten around to resetting the password.
My email is set to check for new messages every 3 minutes. My best time so far is request to complete quote in 8 minutes.
I usually have a drawing, catalog or other hard copy open over my phone. Makes that little red light so hard to see, but desk space is at a premium and it is a small price to pay.
If I really need to know, I walk down the hall, find the person I need to ask or tell something and do so. This has benefits, most people here have food on their desks to encourage visitors. My favorite right now is the giant apothecary jar of animal crackers, but the purchaser with mini Reese cups is right up there.
Decent law abiding people must fear criminals and the law while criminals have nothing to fear.
