Do You Find Value in Taking Staff to a Trade Show?

• Do you think taking staff to a trade show really inspires them? Is that an owners/buyers job and not one of full and part time staff?
• How do you decide which staff members to take the first time? Do you throw a contest?
  After the first contest do you rotate your staff or always take the winners of the contest?
• How many days do you think are appropriate? Obviously hard work deserves at least a day or so to play and see Vegas.
• Do you take your staff to sit with you when picking out merchandise?
• What in your mind is proper when it comes to their pay while away on this business trip? Their normal wage? Per diem for food or reimburse their receipts? Hotel included? Flight included? Link.
