Interesting question.... but here in the United States you are asking about two different fields - so curious if these are combined in different companies.... Business Promotion is a huge Industry here in the US and there is a great deal of literature on Marketing and Marketing Research.... If by counseling you are refering to support Employees to remaining healthy enough both physically & mentally to be productive in the workplace... you are refering to the field of Employee Assistance which is international and there are 7 Professional Associations from Singapore, EU, Canada, South Africa and other continents..... Some EAPs specialize with working with very creative industries like those in the infamous Silicon Valley..... We are in the process of building an International Digital EA Archive out of the University of Maryland.... might want to check it out for references
I would try the creative industries and HR journals for info on this. Journals include Work Employment Society, Human Relations, Personnel Review and Creative Industries. Edward Elgar Publishing has produced a couple of books on this. Another idea is to search 'creative workforce' in Google Scholar. Hope this helps!
