Ever felt like people are taking advantage of you?

As each working day passes, I feel more and more like I'm being taken for granted by my employers. I was originally only meant to be doing three days at the other branch until Christmas; but I'm still there and likely to be there next month the way things are going. If that wasn't enough, they made me go on Wednesday morning after arriving at my regular place of work as one of my colleagues at the other shop was off sick. So I spent morning at the other branch and the afternoon at my own.

It really is getting ridiculous. I feel knackered, unsettled and stressed out. The job's not fun anymore- not that I found it enjoyable in the first place. My parents say don't walk until you've found another job, but if it's getting you down that much, why carry on with it a minute longer? I can see myself saying something to work at some point, and they're not going to like it one bit.
