Pappy, you won't get any info from the currently employed expat group because there are only a few left. Thus to do so, would be exposing themselves. And sadly, there are not many good things to say.
A few hundred expats to a dozen, and now needing them again. Why did they get rid of them or why did they all run away? Name me any successful airline globally where this has happened to this degree. They are fools running under a gov't nationalistic umbrella. Not the place to be. They make money only by pure virtue that the govt takes on the AC financing and the almighty dollar rules over safety and they employ very cheap labor. This combined with old Air Force mentality or in the office still is a recipe fo something...
If you must go to taiwan, work for a real company. evergreen.
Ps: Tip: since you will be commuting, change the law of jurisdiction to your home country. Then they can't screw with you. Expats don't have labor law protections in Taiwan. The companies know this, and now you do too.
