How can we stop our employees from taking our valuable information and using it to compete with us if they leave our employment?

Employment contracts should contain confidentiality and intellectual property clauses prohibiting an employee from dealing with the confidential information and intellectual property of the employer (especially at the time of leaving that employment) – except with the prior consent of the employer. Depending on the seniority of the employee, restraint of trade clauses (which prohibit an employee from working for a competitor of the employer when leaving that employment) should also be considered.
