I just joined a faculty as assistant professor, at a university in South America. The admin team and students treat me as "professor". Moreover, because the official language is Spanish, people refer to me as "usted" instead of "tu" (see difference here).
Just coming out of the PhD, and feeling still "young", I find this treatment very odd. I would like to be treated, particularly by students, by my first name.
Now, without trying to foster authority styles, or exercise power, or being pedantic, I wonder whether there is an actual "benefit" in keeping this formal relationship? For instance, perhaps it gives me more capacity to extract effort from students? Diluting the boundaries might give them confidence to go against my instructions or so. And yet, conversely, someone might argue that a more friendly approach can actually help me gain confidence with students, understanding more their interests and motivations.
In the end my question is what are the pros and cons of each approach, based on your experience. Any help is more than welcome.
