How do you figure that ?
The security staff provide a SERVICE to the homeowner who lives in the community and pays their wages.
They also provide a service to any temporarily invited guest of the homeowner.
While their primary role is providing security, the moment security staff are in a position to interact with people who have some sort of business dealing on site, they are in a service role.
By not doing their best effort to provide that service, they are negligent in their job.
I had contracted security staff removed from our site because of similar attitudes.
(they were also replaced when they didn't do their security role well either)
Both the homeowner and the security staff dropped the ball.
In the end, a manager allowed the trailer in.
That should have been organized in advance by them, or at the very least handled at the time, in a better way.
They make the rules, and can bar access. That is their prerogative. Yet, evidenced by the fact they allowed the trailer in after much ado, they could have done so with much much hassle to everyone involved.
Alas, this lack of organizational skill, and judgement, seems common with some managers, and security staff with little man/woman syndrome. In my dealing with HOA's it's very common. People with little common sense, put in a position of minor power.
The security supervisor did his job well in this case, but it didn't have to get to that point.
