What would you do...

if you had to do a certain task, then undo it, and then re-do it?

Explanation: At the insurance agency where I work, there are HUGE filing cabinets full of client files. Every so often, they need to be rearranged to accomodate new policies, etc. Well, last December I was assigned the job of moving them around, filling in a space of about 4 empty shelves from the end of the cabinet. My task was to shift all the files in such a way that the space from the 4 empty shelves loosened up the space between each file, making it easier to pull out/put in files.
In January, a bunch of policies didn't renew, and we obtained some new ones. When those files were removed and added there ended up being a bunch of empty space in some places and not enough in others, so about 2 weeks ago, they told me to rearrange all the files again so that there was a couple empty rows at the bottom. (So basically UN-Do what I had done in December.) Then, I find out today, that there was a significantly large stack of files on someone's desk for a month that wasn't taken into consideration when I rearranged the files 2 weeks ago. Now, I have to RE-do what I UN-did 2 weeks ago, filling in those empty shelves with the "missing" files. (I can't just stick them on the end because they have to go in alphabetical order...)

I'm pretty sure my boss doesn't know this will be the 3rd time I'll be doing this because the people in the department with the file issues ask a different manager/supervisor to ask me to do the job every time. I'm wondering- should I say something to management? Or will it sound like I'm whining?
