Maybe HPY is not so ethical after all. A lawsuit has been filed (11/15) in Ohio alleging the company underpays reps to boost earnings, falsifies W-2s and W-3s to reduce taxes, defames and intimidates employees to keep them quiet, tampers with evidence and obstructs justice.
Here is the link to the suit on the Ohio court website. Check out pages 9-11 for a summary.
Unfotunately, I believe there is a bit of truth. This suit is coming from the former long term Director of Human Resources. She was terminated after looking into systematic pay issues for the company's sales force. Do your own DD but looks like a situation that could certainly snowball into a much uglier situation.
