My co-worker is trying to sabotage me!! Should I go to HR with this problem?

A tricky situation!

I've been on both sides of this dilemma -- as the afflicted and a manager. Often pettiness, misinformation or misinterpretations are hallmarks of these interpersonal turf wars. Such does not appear evident here if your account is accurate.

Normally I would recommend all the steps you have apparently sequentially taken. Indeed, it was -- as you said -- the mature (and only) approach.

So , the solution?

1) List all you have mentioned here in sequential point form.

Show actions and responses; if possible dates, effects and supporting evidence -- particularly of lost company interests.

Keep it impersonal, unemotional, ACCURATE and brief: no more than one page.

Suggest (don't demand or insist) a couple of POSSIBLE (not mandatory) solutions and request assistance.

Date and keep copies.

2) Arrange an informal meeting with your Director or HR. and present your note with brief verbal explanation. Eg. "I have a situation you may be able to help me with. This should explain it. Could we discuss it sometime?"

3) Being on paper it will have to be responded to. Being non-confrontational they can respond cooperatively. Being informed they can investigate and not be flat-footed in their response when they further discuss it with you.

4) Bide your time with patience.

Don't expect an instant/your preferred/ ANY response.

Don't get uptight or threaten retribution or resignation (unless you HAVE an ironclad alternate position to go to).

5) Remember life throws curves and competence in business can often be secondary to internal politics -- and often the troublesome are experts in politics, if nothing else.

6) If satisfaction is not achieved, stoically forebear continuance whilst contemplating changing perspective or employment.

By the style and tone of your account, most of this you probably have already considered -- but it may help to have it's wisdom affirmed for you.

Report your problem to HR. Let them know you want to quit because of this problem. Come with PROOF. If you can prove it and turn it on her then that will help your story. But nobody should work in that environment. Otherwise you have a lawsuit. She is violating many laws by going into your personal records. Your boss is allowing this to happen and you need to be very careful. You need to have others on your side and looking out for you space. Ask to have your space moved to another office. File with HR. This is a clear violation of your privacy rights.

Yes! Tell your Director, and go to HR. Don't let that sick backstabber get you into any situation that will cause you harm.

Above all, document everything. Dates, times, exactly what she has done. Everything she continues to do. Write it all down. And don't just keep this in your office or on your computer. She knows how to steal, she knows where the delete button is.

Whatever you decide to do, document everything. This girl is just the type to sue for wrongful dismissal or sexual harassment or who knows what. You should report, in writing, everything that has happened to date. You should further get your co-worker to confirm her experience with this girl. From now on, lock up your stuff and treat her with extreme suspicion. This could get a lot worse. Better you be prepared for it.

If she is deliberately undermining you and you can prove it, go to HR and plead your case. If she will do it to you, she will do it to anyone else to gain promotion.Most companies don't want that kind of employee.

From what you have said, you have done nothing wrong and have nothing to hide. Change your passwords to your personal accounts.

push her down the stairs.lol
