There is NO federal law on this; it is a state-by-state issue. Never can an employer be sued for telling the truth, "Pat was fired 15 days ago", since that's true. In many states, a former employer cannot be subject to a suit for defamation for revealing even more details to a prospective employer. A growing trend is to extend "privilege" to the former employer for anything it says about your performance, attendance, or skill. Privileged communication means no defamation suit is possible. Washington employers gained that privilege last year. Check your state rules.
yes
Is a previous employer allowed to tell a prospective employer you were fired when you were not in Nevada?
If they ask, you can't lie. Also, if you list your previous job as a reference or list it under employment history, then you have to tell them. Other than that, you don't have to tell.
No
Yes, if it's true.
You dates of employment and what position you held.
How can you tell that 0.750 has terminated
Don't tell them. That's not something they have a right or obligation to know. All they are obligated to know is that you used to work at a particular job. In fact, if you tell them your work history and consent to them calling a previous employer all they can legally ask is if you used to work there. It will just look bad if you bring up dirt on any previous employer.
No, an employer can only tell a potential new employer that you were terminated. They are not suppose to give any more information than that, however, ther are ex-employers that will over indulge on information.
An employer cannot say you were terminated, but they can say you are not eligible for rehire. Texas is an 'at will' state and can fire you for any reason.
Terminated, If the prospective employer is interested they will ask you in person. Depending on the state, if you do not sign a release of information your previous employer can only state your employment dates and if they would rehire.
Yes. The legal implications would only be if they lied and caused you harm.
