Ive heard that, but Ive also heard that hiring managers can request any letters and all olcc's in an employees file. Ive also been told that if a person does have a letter in their file, it is up to the hiring managers discression on whether or not to send them an offer letter or go to the next person on the seniority list of bidders. Dont know if this is true since I havent tried to move (yet), but if this is the case, I was wondering if it works the same with olcc's.
