Two St. John the Baptist Parish (La.) public school employees won't have to use a biometric time clock that the workers claim violates their religious beliefs. An arbitrator has ruled that the St. John School Board violated the school employees union's contract by requiring the two workers to use the system, which electronically scans employees' fingers when they clock in and out of work. School bus driver Sandra McCray and the Rev. Herman Clayton Jr., an electrician in the maintenance department, filed grievances in February 2007, saying the clocks violated their belief in the "End Time" doctrine. Believers in the doctrine, based on the Bible's book of Revelations, object to fingerprinting and scanning technology.
