Q. "We have to let a staff member go over a moral issue. How do we protect ourselves from potential lawsuits?"
Answer:
Prior to letting the staff member go, make sure you have all of your beliefs in writing with supporting Scriptural references. In 2014 The Supreme Court of New Jersey did rule in favor of a Catholic school who fired an unmarried, pregnant teacher, despite pregnancy being a protected characteristic.
Despite discrimination laws, religious employers do have exemption in some situations where their religious teachings differ from the law.
The best way to protect your organization is to create and implement a Staff Lifestyle Agreement. This document clearly states behavioral expectations for staff members. Reading it and signing their acknowledgment ensures they understand all of your requirements and restrictions.
