Even without a non-disclosure agreement, confidential information obtained by an employee during employment by reason of his or her position cannot be used or disclosed to the detriment of the employer. “An employee is obligated not to reveal employer’s confidential information during employment and after termination of employment.” Nevada codified the Uniform Trade Secret Act (“UTSA” or “NUTSA”) at NRS 600A et. seq. There is a split of authority whether confidential information is protected if it is not covered by NUTSA. These materials will treat all protected confidential commercial information as being contained in NUTSA and all others to be unprotected information.
At termination of employment, an employee who misuses confidential information (customer lists, formulas, etc.), is precluded from using the information and is required to return the materials to the employer. An employer, therefore, at common law, has some protection against disclosure of confidential information even without a valid non-disclosure agreement. “However, an employee can use to his or her own advantage all the skills and knowledge commonly used in the trade that the employee acquired during the employee’s tenure of employment.”
