posting sucks. our units post are told to post on street corners (or 4 blocks of their assigned street corner).
the reality is dispatch doesn't care; you are assigned to a post, and as long as you stay in the same ward, and tell dispatch when you are going to wander away from your post, and are on scene at your calls 10 minutes after you are dispatched, no one cares.
and posting still sucks. SSM is the devils creation for EMS .
biggest things to do when posting are sleep, watching movies on laptop or ipad, surf the web if you bring your laptop, eat, and read books.
btw, while our units are given posts, since we routinely hold 911 jobs that are coded by dispatch as non-life threatening, they usually aren't at their posts long. if they make there at all.
