The good news is that crime that you pled to is very minor and unlike a theft crime it is not a crime of moral turpitude. Moreover, as someone who was a DA for 13 years I know that a 415 plea means that the evidence against you was very weak. The main problem for you is that this happened 5 months ago. A lot of what will happen depends on your company's policies concerning criminal convictions. You need to know what your H.R.'s policies are and maybe consult with an employment attorney. You should also contact a criminal attorney to have your record expunged as soon as possible.
First, check your employment handbook to determine whether your employer has a "self-report" policy. Many employers do, especially those that engage in periodic backgrounds checks and those that employ persons with state and federal licenses and certifications, as most financial services businesses do. A "self-report " policy is a rule that requires each employee to report any criminal prosecution or conviction to the employer within a short period of time after the event. If the employee fails to comply with the self-report policy, the employer will terminate on that ground and will use that non-compliance as grounds for contesting unemployment benefits, usually successfully.
If your employer has no self-report policy, then you do not have an obligation to "approach HR" about this matter, although only you can determine whether in terms of the culture of your employment that would be sound action.
In the private sector, most employers have a general right to terminate an employee for any criminal conviction, but there are some exceptions. You say that your employer is a "financial firm," but that is not a clear description that allows much reliable deduction. Some financial services businesses have a policy of terminating all employees who are convicted of crimes; some will terminate only where the employee has responsibilities for management of client or firm assets; and some will terminate only where federal or state licensing and certifying administrative regulations require it. If your employer is one that bases its policy on state or federal licensing or certifying regulations, then it will not make significant difference that your plea was to P.C. 415 rather than theft. In those kinds of employment situations, it is the facts and circumstances underlying the criminal charge that are important to the employer (and to the licensing or certifying agencies), not the ultimate charge that was pleaded to. And, of course, financial services businesses inevitably consider theft and theft-related offenses to be very serious and closely related to the core-functions of the firm's business.
No legal advice here. READ THIS BEFORE you contact me! My responses to questions on Avvo are never intended as legal advice and must not be relied upon as if they were legal advice. I give legal advice ONLY in the course of a formal attorney-client relationship. Exchange of information through Avvo's Questions forum does not establish an attorney-client relationship with me. That relationship is established only by joint execution of a written agreement for legal services. My law firm does not provide free consultations. Please do not call or write to me with a “few questions” that require me to analyze the specific facts of your history and your license application and prescribe for you how to get a State license. Send me an email to schedule a paid Consultation for that kind of information, direction, and assistance. My law firm presently accepts cases involving State and federal licenses and permits; discipline against State and federal licenses; and disciplinary and academic challenges to universities, colleges, boarding schools, and private schools. We take cases of wrongful termination or employment discrimination only if the claims involve peace officers, universities or colleges.
Christina is correct, perhaps you should consult a local employment attorney with your HR rules.
