So I saw an article on linkedin a couple of weeks ago that basically said it is unprofessional to carry a back pack in the professional world instead of a briefcase. Most of the people who responded said it depends on what field you're in. For example it would be unprofessional for a lawyer to carry one but for people who are in like the IT field a backpack is really the best option.
I can agree with this. Being in the IT field when I have to go out to campus to repair a computer or check out a network problem I carry a back pack. A briefcase would be very limiting when I need to carry various tools, laptops, testing equipment, and cables and stuff.
What do you guys think of this?
