Recently while discussing work with my boss, the name of an employee came up. My boss then said, "oh, he's ****ing Ms. X (who is also an employee). Do I have a right to report this? I am willing to take a polygraph on this.(it's not the first time he does this) Also, do the 2 employees he slandered have a right to sue? And finally, if I report this to Human Resources, can I or do I have an obligation to report it to the 2 employees who he slandered? Thanks for any info you can give me.
