Many of us find ourselves troubled by our colleagues' ethical conduct. What do we do? It's always a good idea to resist peer pressure and maintain high ethical standards for oneself. It's more complicated to raise other people's standards. Sadly, in such situations protesting can not only be ineffective but counterproductive.
Instead, focus on leading by example. Have faith that your team will be the one with the better workers, the more loyal customers, the best results. However, if you see any conduct that puts the enterprise at real risk — whether financial or legal — then voice your concerns, in writing, with documentation, to your HR department.
