Church handbook on employee standards: to uphold Church standards "at all times."
General Handbook: Serving in The Church of Jesus Christ of Latter-day Saints (Salt Lake City, UT: The Church of Jesus Christ of Latter-day Saints), 418
Church employees are to uphold Church standards at all times. To begin or continue employment, they must be worthy to have a temple recommend. This includes employees of the Church Educational System and Church universities and colleges.
Periodically, representatives of the Church Human Resource Department will contact stake presidents or bishops to verify the temple worthiness of current or potential Church employees. These requests may be written or made by telephone. Leaders should respond promptly.
Church employees must comply with employment laws. Church headquarters or the area office can provide information about applicable laws.
