Job Security

In the past 3-4 months I've seen people painting the elevator wall at my work 9 times. THAT'S OVER NINE TIMES IN 3-4 MONTHS!

And it's not that they can't get the color right because the color is fine. I don't even think that it gets dinged up from people getting on and off the elevator. I think it's just job security. Maybe they figure if they don't have any work they'll redo the work they've already done 1/2 a dozen times or so.

First they took down the wallpaper, which was a good thing becuase the seams were coming off and it was a ugly wallpaper to begin with.
Then they started patching the wall. At least that's what I'm guessing they were doing.
Then they painted it a nice toupe color.
Looked great to me.
The next day there was white spakle on the wall again.
That was left for a few day maybe even a week.
Then it was repainted.
A week or two later we saw a couple guys repainting again
Then the next day they were painting again. Really how many coats of paint does the poor wall need?
This went on for about a month.

All seemed fine until about a month ago when the white spakle appeared on the the wall again.
I did see some workes taking the ugly wallpaper down from the sides and back of the elevator walls so I figured they were back to finish the job they originally started.
The wall was repainted the same color
Then the white painted appeared
Then paint
Then white spakle/paint
This has been going on for a month!

So I figured our building is the painters job security. There is noone ever here but each night the wall is either painted or spackled.

When will the madness end?
