In New York, no law that requires employers to provide employees with access or copies of their personnel files. However, a party in a lawsuit could compel disclosure of the file through a subpoena. Some other states, such as Connecticut, do have laws that provide employees access to personnel records. Some employers have a written policy that allows employees to review their personnel file. If your employer has such a policy, then you should at least be able to look at the file, even if you can't get a copy. Good luck.
No, unless you are in ongoing litigation and the file is pertinent to your case and has been requested in discovery.
