Why are some people so power hungry?

In my new job I am filling in for a girl on Maternity leave. She will be working one day a week from home to oversee my work. Thats fine, but she would have to be the most power hungry control freak that I have ever met and the way she speaks to other staff memebers just sucks. She is driving me insane. I was given 1.5 days of training...thats it, and she expects me to do the work more accurately than she did and at the same pace....hmmm, yeah right. Not only that, but the sales have gone insane and another girl I work with is getting snowed under. So much to do in the job.
Anyway, today she will be in the office and will get on my case..honestly, I will be biting my tongue the whole time. She is to train me in doing the pays today so I will see how we go. If it gets to bad, I think I will talk to the owner, I will not be treated like shit by anyone and they are hardly in the position for me to say stuff you.
My back is improving gradually, still quite sore and stiff and its affecting my sleep. Last night, the federal budget was on the TV and I just crashed out at about 8pm. Still have to get the car to a panel beaters to see what damage has been done to it.
The kids are all great. Stef is obviously missing me as every night when I walk in the door she wants lots of cuddles and attention. Its great in some ways...at least she shows affection and misses people and thats quite rare with severely autistic children. Brent resat his failed Maths SAC yesterday, hopefully he showed enough of his working out to pass this time. Melinda is disorganised, and it drives me mad as I can see her being just like me. Yesterday she again left behind her bus money....grr...at least she made the bus after all. She still doesnt bring home homework, hmm, must talk to her about that. Jack forgot his ritalin yesterday and was apparently a total pain in the ass at school. I really must get a new script filled and get it stored at school.
Got some replies to finding a nanny...it will be great to sort out that so that the kids are organised and settled in routines. Maree our guardian angel is great, but although happy to do it right now, it is way too much for her and ties her down too much to do it all the time.
Thank goodness we have respite care this weekend. I really need to get well and truly pissed lol.....to reset the stress clock and to make myself relax. A damned good bonking is required too (lol, Steve, I know you read this). I am definitely a rock chick, ...sex and drugs and rock and roll.....(leave out the drugs and insert alcohol)!!
Anyway......its 6am, time to get the housework done!
