There is no legal obligation upon an employer to provide a reference.
If a prospective employer calls your previous employer, the previous employer can say whatever they feel is true. If you don't want a bad reference, you may not want to put your previous employer on the application.
"What if previous employer will not return a call for a reference?"
Only if individual has provided written consent to previous employer allowing them to provide this type of information. Assuming said contact is being used as an employment reference, NOT a personal reference.
Employers usually ask applicants their reasons for leaving a previous job. Potential employers may call the previous employer for a reference.
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.
Not at all, if the former employer was disatisfied they have every right to inform future employer, if asked.
Yes if it relates to your job performance.
Is a previous employer allowed to tell a prospective employer you were fired when you were not in Nevada?
Nope, but a reference check will do the trick. If they call your past employers for a reference check, they'll more than likely find out.
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.
They can only state whether you worked there and what dates.
The only things that a previous employer can say are #1- if you are re-hirable and #2 - what dates you were employed there. The problem is that in order to take legal action you have to be able to 100% PROVE that the previous employer said more than that. An employer can give a negative reference for a former employee if they wish to, but they are not required to. The employer may be exposed to liability, or at least to the expense and distraction of a lawsuit, if it gives such a reference. The former employee may allege that the information provided was false or misleading. The burden of proof would be on the employee to prove what the employer said and how it was defamatory. Truth is a defense to the employer. For this reason, many employers have policies prohibiting giving any reference, positive or negative, and will only confirm the dates of your employment and last title. Some employers may disclose if you are re-hirable, but a non-answer or negative answer to this question could again expose the employer to claims.
