Why are they having a strike in Bangkok?

Well, I'm Thai, and I have to do this current event. I found a good website that I can do it off of, but this website doesn't tell me the whole thing. The website is a href="http://www.msnbc.msn.com/id/26498577." rel="nofollow"http://www.msnbc.msn.com/id/26498577./a The main thing that this website doesn't tell me is the question why. Like why are they striking? Okay, I know they hate the prime minister, but why? And in that website it says that they hate George W. Bush, but why?
