Today at work I went to get a notebook computer that I had stored in a filing drawer and it was gone! Fortunately it was not my primary work computer and I had not used it for several months... so no work lost.
Just this Monday another guy in our office noticed that his personal optical mouse that he brought up to work was missing, but didn't make much of a fuss of it.
Damnit, this is frustrating. I trust the people I work with... we have a great group... so there is no one I can logically conclude to be a suspect, and I hate to automatically blame the night cleaning crew.
On a side note... my supervisor has been out of town for a meeting having to do with the new budgets and corporate plans and other such things. Basically that was the meeting where he was going to find out if the new budget would allow for me to be hired as a perm employee (for those who don't know, I am currently a contractor and I've been trying to get a perm job for a long time). When I called my supervisor to tell him about the theft, he let me know who all I needed to contact and what all to do... and wrapped up the phone call telling me that he will likely have some "good news" for me when he gets back!
