Wow! Thanks for finding the original for this.
Though I had to use google translate to read it, it pretty much summed up my ideas that this individual is:
a) Jealous of ALT income (continually referenced over multiple years)
b) Jealous of Flex hours (note, she never mentions if the ALT comes home late, ever)
c) Does little research into the ALT itself (ie, could the ALT be getting off at specific times because they do night classes, mandatory eikaiwas, etc...)
d) Seems oddly prejudiced (2010/late 2009 posts are complaining about the ALT being FAT, All foreigners must smoke weed)
e) Finally... Looks like a stir crazy house wife!
Obviously she has some real complaints, like the ALT running the washing machine at midnight, but for the most part its just general grumbling. It's also nice to see her looking at the JET programme as a whole and making a judgement call that it largely hasn't done squat to improve English in Japan over 21 years and that it has cost quite a substantial sum of money as well. I also liked that she wasn't terribly keen on the silly games ALTs play in the classroom, rather than teach... It made me smile as someone who isn't that fond of games in the classroom.
As I read more she really goes out of her way around 2008 to find ways to hate on the whole ALT system as a whole. Like REALLY going out of her way to find stuff.
Though all this being said, if this ALT really did only have to work half days, can we figure out where this placement is? I would LOVE to have it
(Is it possible that this ALT wasn't a JET and the woman just assumed she was? ... ie was this person maybe an Interac or something working part time?)
