I work as a system administrator/architect at a partner of a big IT company, been there for almost a year. Almost a month ago I was allocated the task of studying for a specific certification needed so that my company can take a certain project, and I got the certification and we got the project.
Now, I got the chance to shift my career into a path I am much more interested in with a better salary too. I have not signed any loyalty paper nor do I have a clause that oblige me to stay for a certain amount of time or pay anything regarding the certificate.
Is it be unprofessional of me to tell them that I want to leave and that I no longer want to be a system administrator?
