The dean of the Methodist University College's Business School has posted this announcement regarding their take on appropriate dress at the University. Not sure if I will be expected to wear a tie when I am teaching classes with BBA/MBA students, but I've packed one in my office desk to be safe.
Having worked at United Parcel Service headquarters, I recall having been concerned that I dress according to the style expected of lecturers here. The Principal set my mind at rest, saying that there was no formal dress code at the school last year. I understand that the "casual Fridays" rule at UPS Headquarters may be extended to the non-summer months - it seems that in the US, dress codes have fallen into disfavor. During the 1970's when I worked at Chevrolet's Central Office, we were required to show up in suit and tie, but could park our suits in a closet in our office unless visiting customers/clients.
Another interesting aspect of the document is the use of a wide variety of fonts. The Ghanaian, once he masters the use of a computer to typeset documents, tends to go overboard with the idea of clip-art and weird fonts. This particular document had only one font family (Times Roman), but included three different sizes, bold, and ALL CAPS (which from my perspective seems like I am being yelled at). Not sure that the Ghanaians feel the same way, however.
