Yes. The legal implications would only be if they lied and caused you harm.
Is a previous employer allowed to tell a prospective employer you were fired when you were not in Nevada?
I don't know about in California but I heard that an employer is not allowed to tell anything about an ex employee unless used as a reference. If you just use the employer as a previous job all they are supposed to be allowed to verify is that you did work there and the dates. However if you put them down as a reference and a prospective employer calls them they can elaborate on your character as well.
Employers can ask that in every state.
Background checks are unregulated.
You dates of employment and what position you held.
I don't believe they can. There are only very GENERAL questions an employer can ask about a previous employee.
The only questions they are "supposed" to answer is How long you worked there and What type of employee were you considered while under their employ for the specific job that you were hired to do. They can verify the amount of pay you made and if you were punctual.
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.
No - can only be required to verify employment
Yes. However the previous manager does not have to comply.
Employers are NOT restricted in making factual comments on former employers. They are liable only if they make knowingly false statements. Prospective employers can ask about your former job, too.
A letter of transfer letter is a letter from a previous employer to be received by employee's new employer for recommendation. This usually happens when the employee is transferring to the same franchise just a different location.
