Q: Can my job fire me for not telling them I have a mental illness?

A: More information is needed to explore your situation, but this certainly sounds like it could be an unlawful practice. You should consult an employment law attorney in your area to discuss.

A: Your question isn't about employment law. Rather, it is about contract law. So long as the subject in terms of the contract do not involve contraband or other illegal activity, it has long been established that a person's right to contract is unlimited. Nobody "makes" you do anything. What you meant to say is that you were required to execute the document you described as a condition of employment. That means that you had every right to decide not to sign it and not to work for them. We cannot explore the reason for the provision because we do not know and any discussion would be pure conjecture. Once you execute the agreement, you agree to be bound by it. That said, depression and other mental illnesses can manifest themselves at any time. So long as you were unaware of any mental illness and or no mental illness had been diagnosed at the time you executed the agreement, a later diagnosis of mental illness would not be a reason for dismissal, under the agreement. Dependent upon the type of work you do, there may be multiple reasons why you should not perform that type of work if you are suffering from mental illness. That part of the analysis requires far more information.
