If you are a government contractor, one of the last things you want to see is your customer getting embroiled in the workplace problems of your employees. When your employees complain about workplace issues to the government customer, you invariably end up with an irritated customer who questions your ability to manage your workforce — not exactly the kind of performance review that leads to more business. And so it makes for good customer relations — and thus good business sense — to direct your employees to keep all of their complaints and issues internal and to bar them from bringing such matters to the customer.
