I am deeply sorry to say that if you are locked up in the office or a building, don't blame the security guard but YOUR SELF. If that guy did not lock the door, you would complain. If he does, you would also complain. Funny that you don't keep the security phone number in your mobile.
On Sunday [20 Nov 2011] at 0745 hours I received a SMS to post 2 security guards at the new HR office which is at 6th floor. By 0800 hours I received a report from my security guards that nobody is in the office, the door is not locked and foods for that floor is already delivered. And so, the not well educated guards assumed everything is fine. I would assume the same if I were a security guard.
My humble opinion; security guards are always treated like monkeys. HR knows we are short of almost 20 guys. More than 40% are old cocks, sick, weak and mentally very negative. Yet when they are cornered by their bosses, or incidents occur, the scape-goat is always the security office.
Anyway, life must go on. I will give my best with whatever I have. Say what you like, I will drill my security guards to serve you all. because I don't work for you, I work for the university.
