Those that are job related. For example an employer may not comment about an employee's or former employee's sexual orientation.
A former employer can answer any question it wishes, without limit. If it answers factually, it can never have liability for answering.
You might ask them if there is a better way of doing your job. You could ask them for help or suggestions on how to do some things.
Answerif you were fired from your previous job, keep it to yourself. Legally your previous cannot devulge anything nagitive toward you. Most employers look at your refs to see what you wrote, but honestly they rarly call the references, and if they do, legally all you previous employer do is conferm that you worked there and for how long, and what your job function was, they cannot legally answer any performance related questions, nore can the say why you left.
Yes. Legally, they are allowed to say anything that is factual and accurate.
what position did you hold at your previous employer
I don't believe they can. There are only very GENERAL questions an employer can ask about a previous employee.
Background checks are unregulated.
The list of questions that you can ask, or rather that they can answer is much shorter. Did they work there How long When did they leave
It can certainly happen. Legally, they can say anything about you that is factual and accurate. If they are called as a reference, and most times they will, they can answer basic questions as long as they do so truthfully. They cannot slander you or reveal personal data about you.
The only questions that are truly legal are if the employee worked their and what their position was. They can also ask if they are eligible for rehire.
Legally your previous employer cannot give a negative feedback to a potential new employer. All they can do is verify employment, dates of employment, and the position held by the employee.
When an employee indicates they didn't get along with a previous supervisor you should ask more questions. You want to ask questions so that you can discover what caused the problem.
Is a previous employer allowed to tell a prospective employer you were fired when you were not in Nevada?
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.
