I didn't realize until reading these stories that what I had done was stop a PA person in her tracks.
In my department, there are four stations. There is one employee in charge of each section for five days of the week. On their days off, the floaters fill in at those stations. I am a floater (until March 1st!) as is the other employee in question. On the particular day in question, I was assigned to a station and she was assigned to float. That means that if, say, station 1 needs paper but it is stored in station 2, she goes to station 2 to get it. Her entire job that day was to run errands.
Coworker is a busybody, constantly telling other people of the same rank what to do. She has no authority over us but likes to act like she does. We are allowed to use our discretion, and if she doesn't agree with it, she'll come tell us and undermine us in front of the inmates (big no-no). For example, there is an area in which we're supposed to only allow 5 inmates. When it is really cold outside, some of us will allow 6 inmates in there instead. Coworker saw that another coworker had 6 in there and she opened the door, didn't even look at the other coworker, and said, "There are only 5 allowed in here, one of you needs to leave". The problem is, we've been told we're allowed to break the rule at our discretion, aka when it's cold out. She just doesn't like it so she pulls stuff like that. (I have a lot more stories).
I was in my station and decided to let my workers (the inmates) take a break for about 10 minutes. During that time, coworker came to grab something out of my station for another. When she saw that I had given the workers a break, she said, "You know you're not supposed to do that, right?" After having had enough of her trying to control every little thing everyone else did, I didn't even look at her. I answered her question, that was it, no more, no less. "Yes, I know," and kept doing exactly what I was doing when she walked in there.
She just stood there expectantly waiting for me to keep going or to challenge her. Eventually she gave up, sighed, and left. What? I answered her question, didn't I?
