Not On Such A High

I knew it wouldn't last long!
My bubble burst today, well slightly, when I found out some information that I maybe shouldn't have about some of my co-workers.
As a supervisor I liaise between the guard force and management concerning various matters. One of these things is wages. One of the guards came to me with a wage query (something which we have to do regularly with this new security company). The guard was one who had come over from the new client's old building. He was one of a small group who transferred to this building once all the client's staff had moved and the old building was no longer being used.
By the time they had moved across, almost all the hard work had been done (getting a building site up and running as a working occupied building). The guards who were already on this site, myself including, were told that we would not be getting a pay rise for probably at least a year, despite out dramatic rise in duties and responsibilities.
I have just found out that this guy, from the other building, is on more money, as a guard, than I am on as a supervisor (or as an acting manager come to that!). It shouldn't bother me as much as it does, but the fact is these guards have been able to pick and choose what hours they want to work, what shift patterns and what duties they want. All the staff who come from this site originally have been lumbered with the rest and lost all of their overtime, practically halving some of their take home wages! Half of these new guards are people I would not want to work with ever again, because of their lack of professionalism and ability, poor appearance, lateness and all around lethargy.
I am really not happy about this and will be mentioning it to my boss tomorrow when she is back from her day away to one of the client's northern offices.
It has certainly ruined the high I was on since Monday afternoon. I'm almost tempted to tell them to stick their secondment! Almost!
