Exhaustion??? Burn-Out??? or just plain tired???

I love my job at KSD. Can’t get enough of it- I think I have found my “second home” there. But I work part-time at this “one place” and I was in training from April until October. I got to travel for training this summer. When I got there I was to have had my work videotaped- and goals set. I did not know that! I felt like an idiot. My boss scheduled me a couple of different times- every time she would forget – and not show up!  I found out this week that I don’t know if I got my pay raise or not- because my login to the system is screwed up. I have had to reset my login abou 6 times in the last 8 months… They use a finger verification with our time clock- had to reset my finger AGAIN!!!  It is so darn irritating!  I had a customer yell and complain about something that was out of my hands- I have no control over the othe customers.. it really ticked me off- then I had some very impatient customers after that… so I left the part-time job early.  I just don’t know if I am a good match there????  I really want to quit. I feel like I am totally getting screwed over there. I just get so frustrated. I don’t get to spend time with my son- or husband because of it- but at the same time I like getting the paycheck. I just wish they would get their act together. Other people that started the same time as I did have not received the same treatment I have. They haven’t had any of the trouble I have had.  I just want to say “buh bye!” AAAAA!!! With Bud unemployed I have no choice in the matter.
