With so much negativity it is hard for us, the readers, to judge the relative situations at the various airlines.
While I agree that a lot of what is posted falls within the category of "emotional", a lot of specifics have also been posted. Specific violations of contractual language, reductions in terms and conditions and questionable hiring and firing practices to name a few. There is more than enough information here on all of the ME carriers for you to accurately judge how you will be treated. It's up to you to figure out how that compares to your present situation and whether you will be able to put up with it in the longer term.
