The boundaries of religious expression in the workplace — a cause defended by an over-broad coalition that links religious minorities who wish to wear required religious clothing or hairstyles with conservative Christians seeking to proselytize their co-workers — become a little clearer this week with the ruling of a California Appeals court. The 9th U.S. Circuit Court of Appeals in San Francisco separated the two claims in deciding the case of Daniel M. Berry, a county social services employee who had sued his department for the right to witness to social services clients and employees. The court ruled that Berry’s stated intention to share his religion unless restricted threatened to entangle the municipal office with Berry’s religion, and therefore that his request could not be accomodated.
