I started teaching this year. Since at the beginning the idea was just to do exercise sessions and now it starts becoming very (maybe too) time consuming with slide preparation, correction of homeworks and exams, I'm considering the idea to quit teaching.
My impression is that the time spent teaching/correcting/preparing is affecting very negatively the amount of time I spend in the research and the quality of my work.
Since from an economic point of view there are not a lot of advantages (roughly +10%), in the principle my idea was to earn teaching hours for a possible future in the academia, even without being sure about my future.
Since I have no idea about what to do after the phd and one of the possibilities is industy I was wondering whether ≈ 200 hours of teaching are seen positively from an industry perspective or if they are totally unnecessary from who is planning a future in the industry.
