Several factors need to be considered to determine whether you have a case. Colorado is an at-will employment state, so employers can terminate an employee for any reason or no reason, so long as it does not violate public policy or statutory protections. 

Your employer’s reliance on an unspecified “source” to initiate the investigation does not inherently raise legal concerns unless the information provided was false and defamatory, or the employer failed to conduct a reasonable investigation. That being said, your employer’s claim of “dishonesty” as a policy violation must be supported by evidence. This could be a point of contention if you were terminated for dishonesty without clear evidence or an opportunity to respond. 

Colorado law offers some protections regarding criminal cases. Under C.R.S. 24-5-101, an employer cannot use an arrest or pending charges as the sole basis for termination unless there is a conviction or the charges directly impact the employee’s ability to perform their job. 

While your termination may not automatically qualify as wrongful under Colorado’s at-will employment law, there are potential legal issues related to the employer’s investigation. Contact an employment law attorney immediately to determine whether your situation could constitute a wrongful termination case.
