legally, many people are surprised to find that there really is nothing they cannot say that is true. They can say what ever is true, that they want.
What they can legally not do is:
disclose private medical informatin (hippa
disclose personal information such as address, SSN, (privacy act and social security and ID protection act)
The problem is, so many people are accusomted to HR and others telling them they cannot say certain things, out of fear of litigation, that it has become ingrained in our culture, that certain things can not be said.
If acompany says something dispareging to you, and that causes you to not get a job, they are at risk for litigation.
your previousl company can reveal what ever the truth is. For example:
They can say you were terminated for cause. then when asked what that cause was, they could state it. It gets litigious form there on. Lets say cause was theft; they could say that, and you could lose a job because of that statement. BUT, in reality, theft was never proven, it was merely suspicion of theft......So you take them to court, and win a hugh settlment because of wrong ful discharge or lack of due process to prove theft, after revealing it to a potential employer.
Most emlpoyer will take a safer course of response such as: we no longer had a need for her talents. Or we were not a cultural match. such things as that.
since you were the person let go, you can say what ever you like. However, ther is a tactical error in saying anything derogatory about your old employer or supervisor. That is a killer in a job interview. Whle you can legally say anthing you like that is true, it will nto be good in an interview to state anything derogatory.
A safe response for a canndiate is similar to the former emlpoyer: we were not a cultural match; they were a great company, but there were issues based on values that I could no longer support, and so forth.
LEGALLY: you can either one say what ever you like that is true.
