I don't necessarily fear the unknown, but I suffer a great deal of stress when bad happens spontaneously. This is probably just my need for order and plans here, but that's what happens.
On another note, I do feel incredibly uncomfortable in a situation where I have to do something I've never done before, or if someone expects something of me and I don't know *exactly* what it is.
Let's take yesterday and today as an example. First off, I have no problems whatsoever with working overtime, or coming into work on a day off. I can do that.
Here's what I loathe: The impulsiveness of it all. It's not that they call me in that bothers me.....it's that they do it at random. It would be so much nicer if, at the beginning of the week, they say, "Hey, we might have to call you in later this week" because then I won't make plans.
I know that's highly demanding and impossible, because people are infamous for having emergencies and not being able to show up, or just being lazy in general. But it's horribly inconvenient when I've already planned my whole day out, homework included, and they want me to come stock their creamed corn. (Which isn't even my job, technically. I'm the produce guy.)
But hey, it's extra hours. And it looks good to management. It's a win - win, minus the terrible inconvenience. ; )
