T-N-T Motorsports v. Hennessey Motorsports, 965 S.W.2d 18 (Tex.App.-Houston (1st Dist.) 1998, pet. dism'd).
Certain duties, apart from any written contract, arise upon the formation of an employment relationship. Miller Paper Co. v. Roberts Paper Co., 901 S.W.2d 593, 600 (Tex.App.-Amarillo 1995, no writ). One of those duties forbids an employee from using confidential or proprietary information acquired during the relationship in a manner adverse to the employer. Id. This obligation survives termination of employment. Id. Although this duty does not bar use of general knowledge, skill, and experience, it prevents the former employee's use of confidential information or trade secrets acquired during the course of employment.
