Pros
Easy work, if you do not go above or beyond to show you have actually IT experience you will go far. Can watch Netflix while pretending to work if that's your thing and nobody notices.
Cons
Unprofessional managers that are in collusion with HR when there is any justified complaints. If you stand out in IT knowledge you paint a target on your back and you get false negative yearly reviews from a manager that gets the information from a supervisor who has it out for you. Good ol boys club, to advance it's who you know vs what you know. They use you for your knowledge and promise raises and promotions then renege on it after you are done with said project which was well beyond your job role. Complete collusion and sabotage to oust you from the company and HR allows it / turns a blind eye.
