Boss trying to make you an accomplice
Be extra mindful, when your boss tries to intimidate you into doing things that are against company policy or breaching the law. This could definitely be to your ultimate disadvantage. Decide coolheaded that the threat she implies (blocking your career, making your life miserable, etc.) is true. Clear up the situation with a loud and clear no even if it costs you your job. Set down everything in a memo and email it to yourself. You thus had a dated information to use in the future in case the situation called for it. If you have little power, you can quickly be shut down if you try to blow the whistle. Get others on your side to blow the whistle with you.
