If like me you are a static guard then your role is to act as a physical presence / deterrent on a site.
You are the eyes and ears of the company. It is your responsibility to make yourself aware of what is going on, on your site.
I work as a lone worker, which obviously means I work on site alone.
Other than the occasional visit from a mobile supervisor and chats with construction workers / residents / other people in the area, there is little human contact. In fact any form of human contact I did not mention is pretty much unwanted contact aka people breaking onto the site.
You are not there to physically restrain anybody or take them on. Like i said originally you are eyes and ears. You patrol the site at random times and write down where you patrolled / what the result of the patrol was. If something happens for example an intruder you report it to your control room who will react accordingly.
As for magazines and the internet... I guess thats up to you. You will most likely be expected to work long hours on your own which can be very very very lonely. You cannot be expected to be patrolling constantly and will spend a fair amount of time in your cabin. If you want to stay sane then you need to keep your mind active by doing something, so keep yourself busy.
Personally I happily mop the floor of the bathroom and my cabin, wipe the desks and the kitchen side.. .keep it all nice and tidy so its a nice place to be. I do this to pass the time and to make myself feel better.
I also make it my business to secure anything on the site which is unsecure. Sometimes the builders will leave a fence broken etc... so if i can repair it I usually will, it makes my job easier in the long run.
I take a laptop and go on the internet too, or i used to take a portable TV. I also read newspapers / magazines / listen to the radio (a digital radio can be a god send). Reading books is a good idea too, so you can learn while getting paid. The company you work for will no doubt have rules against anything other than a radio, but I have found that you just do it anyway, they know the majority of guards have a TV or something.
I popped onto my site today to ask the other guard something, and that guy was on his laptop watching a DVD while studying for university. They all do it. You have to keep yourself sane.
Its ok for someone in a cushy office doing 9 to 5, sleeping in their beds at night, seeing their family and friends to tell you your not allowed this or that... but you gotta make the best of your own situation, no job is worth losing your sanity.
Saying that... dont neglect your duties. If i am watching a DVD i will only do it with very low volume and with the window open so i can hear if anything out of the ordinary is happening, i also force myself to patrol on a regular basis.
ALSO..... DO NOT fall asleep. That is just wrong, and will put you in danger.
