I just quit a job as an English teacher to be able to pursue an internship in my university that pays more per hour than my previous job. I had never quit a job before, and it was quite a sad departure, as I developed a connection with my co-workers and boss before abruptly handing in my resignation for the above reason.
While my dad doesn't disagree with me quitting to be able to study and have better networking opportunities in my career, we had an argument about how I'd have no qualms quitting any job if I was offered a comparatively better position elsewhere. He says that I shouldn't put my reputation at stake for what seems like good opportunities, and that employers would see me as volatile and disloyal.
I'm wondering what your opinions are on this discussion, because to me I believe that changing jobs is the best way to increase your salary.
P.S.: I'm studying Computer Science.
