This is an ethics question.

I have a phone provided by certain company. Recently a number of people that I know have started working for that same company. Now theres other people that I work with that seem to know certain things about my calls that should be impossible for them to know unless one of the people working for the phone provider has accessed my records.

Should I call up the phone company and ask for the names of every employee that accessed my account? If they have accessed my account records and gave that information to third parties would that be a violation of U.S. law? Would you seek some sort of recourse if something like this had occurred with your account or just blow it off?

May be I'll just change providers and be done with it.
