Can a current emloyer give out your salary to future employers?

Answer 1

I'm an HR major and I don't believe there is any restriction on providing that information. If you don't want that given out to prospective employers, you can always provide a note to your employer stating that you do not want that information released.

Legally, they can give out any factual information, but not opinions.
For instance, it is an opinion to say you have poor attendance, but they can say you missed XX days in a year because that is documented. They cannot say you were rude, but they can say that you had an episode where you were violent. Although most employers will avoid giving out that information!

Legally, they do have to give out your job title, and dates of employment.

Answer 2

If you sign a release for background checking you are releasing former and current employers from liability if they give out truthful information about you. This could include job title, duties, attendance, salary and if there were any performance issues addressed. (were you written up or fired for violating a company policy)

Not opinions, just truthful information that is applicable.

Answer 3

They are allowed to if asked. Alternately, many companies ask you to provide a previous pay stub to prove employment and salary.
