Backdating employment contract
You might assume the worst in people, so you might assume that they would use the backdated NDA against me, lying in court, which would be another good reason not to sign it. It is possible as Colleen points out that there are motives that are not malicious against the employee.Conclusion: No matter what your assumptions are, don't sign it. In the case described, someone intends to make someone act differently by providing a forged document.While it's likely a non-issue, it's important to protect yourself.One possibility I haven't seen covered is the chance this is an honest mistake.If you think someone might want a good reason why you don't sign: Well, obviously by having an incorrect date you would be effectively lying - you would make it look like you signed two years ago, when you are signing right now. Rather than try to balance your loyalty to the employer and loyalty to your principles (and generally the truth), I strongly recommend not signing the backdated document.
Ordinarily that wouldn't be an issue for me but the document is backdated to the start of the project so that it looks like I signed it in early 2014.
Can you please update the date, and then we can go ahead and sign? A backdated NDA is valid from the point you sign it, but appears to be valid from an earlier date.
