The answer seems to be a big NO, according to a recent newspaper report http://www.dailymail.co.uk/news/article-2112712/Health-chiefs-blow-10k-telling-staff-SMILE-often.html
According to the newspaper report, the staff felt that the Active Caring for Everyone (ACE) scheme was patronizing. Staff were encouraged to show 'ACE cards' to staff that weren't smiling at patients. The newspaper report doesn't provide too much detail, but is sounds as though the scheme had a 'pop-psychology' feel about it. Indeed, the reaction of the staff may be an interesting example of extreme emotional labour.
