There is a sense, however, of a seminar being a bit more of a traditional training session, with the preponderance of time spent in presentation of material from the front of the room. A workshop seems to imply relatively more time spent interactively, perhaps in facilitated activities, where the participants generate some form of product (e.g. goals for the coming year, a strategy for dealing with a customer, etc.) at the end of the session.

Definitely your organisation staff need to attend workshops either seminars if you want to remain  competitive in this contemporary technology-driven environment.
