I have been told that EOE rules say that all a potential employer is able to ask of a previous employer is lenght of employment and are you eligible for rehire. Today I had to fill out some paperwork for them to contact previous supervisors for info and along with the above info there was a checklist of about seven items such as reliabiltiy, works independently. This is a big comapny and I am pretty sure they would know the rules so I am wondering if what I have always thought to be the rules are true. Even when leaving my former employer I had asked my supervisor if I would be given a good reference if contacted for a future job and he said "I am not really allowed to tell them much other than if you are eligible for rehire and you would be".
