social or informal recognition. We defi ne this type of recognition as an individual and/or group (thus the use of the term social) provid- ing contingently informal genuine acknowledgment, approval, and appreciation for work well done to another individual and/or group. This informal recognition is provided typi- cally on a one - on - one personal level (thus the use of the term informal), verbally, and/or in writing/email. Besides social and informal, we also emphasize the qualifier “ genuine ” in this definition because it does not include phony praise, “ attaboys ” (or girls), a smiley face, or a pat on the back. This type of recognition is also given contingent upon exhibiting the desired/relevant behavior(s) that has a favorable impact on desired performance outcomes.
