In a typical spa massage setting, it's normal to tip a massage therapist for the session. But corporate massage is different, largely because it's someone else who is paying for the massage service.
Your massage therapist in a corporate setting will not be expecting a tip. We've worked the total price of the massage event or program to include the cost of a tip, so your therapist is already going to be making more money for their work to begin with. However, tips are always appreciated.
There is no expectation or requirement from your massage therapist, or from Incorporate Massage, that you should offer a tip following your massage session.
