Is it unethical to work for 2 professor (2 seperate research lab in two non-related fields) at the same time? I am a undergrad student currently working for professor A as a full time research assistant co-op job. On the other hand, I volunteer using my spare time working for another research lab of almost unrelated field. Professor A doesn't know about this.

So my question is, is it unehtical for me to do this? If you are Professor A, and it happens that you find out I work for another professor simulatenously, would you be pissed off?

Do you think this will destroy the relationship between me and any two (or both) professors?

I ask because my friends warned me not to do this. On the other hand, I don't think it is too much of issue since I am not stealling data or anything from any one of the research position AND more importantly, they are in two different non-relating field.

Similiar question is asked here, but it is different because I am asking from a "ethical" perspective.
