I also worked at CDI from 2008-2009. They continuously changed my contract on me, tried to screw me on vacation and did not pay me my whole salary my last month. It certainly was not me, I am currently a TEFL Trainer and was well loved by my students and co-workers. CDI just has many branches and each branch head gets to change your contract on you without the approval of the HQ. Beware. They screwed everyone else I know who worked for them too.
