I think intangible benefits we can count of workplace wellness programs are relief in stress and for employers these programs make his employees more loyal. We take service from Truworth Wellness (http://www.truworthwellness.com/) and I personally feel that.
Well if by intangible you mean unclear and undefined, then all of those responses above are off the mark. Because all of the above responses are actually research supported. All are measures of effective wellness programs.
While loyality itself, (Karin’s post) may be a questionable tangible, we do know that potential new hires value companies with wellness programs more than those without, and that employees looking for new positions consider wellness programs as a negotiation strategy.
Stress relief and team building are two huge benefits of this. Plus there is always a chance that it leads to improved mood, improved function at work, improved work quantity/quality.
