No, you signed a contract to help your employer accomplish their mission or goals. Your contract does not include the revelation of how you get your job done. If you can get it done my automating tasks, that is perfect. No companies has been ever created to employ people. The mission of a company is to raise fund and make profit for it to survive and strive. No individual is indispensable. Even the CEO gets fired if she is hurting the company in any way or fashion. What is important is to invest the time you save into what is important to you like family -taking care of kids or parents, doing errands where there is no traffic, doing chores, volunteering with other organization...What is even interesting and important is to spin out an application or a company out your skills to guarantee to get additional income with your spare time and build assets with the additional income for your family. You are working for yourself in the confinements of your employer systems. The unethical matter will be lying about your process when someone asks you how you do your job or there is a company or code or rule that spells out "Do not automate your tasks or job." Introducing bugs to deceive is unethical. Introducing bugs to test the resilience or the reliability of your scripts is highly desired.
