If you have a concern, please speak up. It's a simple truth of human life. What's complicated is how most of us deal with conflicts or, in many cases, don't deal with them.
Conflicts arise out of unmet expectations.
An employee may make assumptions about what will satisfy a customer's expectations. A customer may make assumptions about what a product or service can deliver. When expectations aren't met, that often triggers disappointment, frustration and anger. Some people feel so upset they don't even voice their concerns. That's a missed opportunity.
