Legally they shouldnt disclose any of that information. They are legally only allowed to say when you start and when you resigned. They legally cant say what kind of employee you were even if you were a complete tool.

In our industry they fool a lot of us with threatning our future...If you suspect they did that you, take legal actions...We shouldnt put up with them threatning or telling us they will tell Delta or whoever 10 years down the road what kind of employee we were...That's defarmation of character and slander!
