I work as a full-time employee in industry. Recently, I've been invited to present at a conference in an area not closely related to my degree. My employer approved me being absent for two-three hours and I accepted the conference invitation.
However, I'm not sure how will this look in the eyes of the conference attendees and other presenters since I will have to leave immediately after my 20 minutes talk. Therefore, I will miss their talks.
Is there an etiquette regarding this? Should someone accept a presentation on a conference if they won't be able to be present for the whole duration?
