SALT LAKE CITY (AP) — Brigham Young University has banned beards for most students and faculty since the 1960s, when they were seen as a symbol of anti-authoritarian rebellion. But attitudes and enforcement of the policy at the Mormon church-owned school have relaxed in recent years, but some want even more change.

Nearly 5,000 people have signed a petition to end the school’s beard ban, The Salt Lake Tribune reported.

The school approved beards on campus in 2015 for Muslims, Sikhs and other students to honor their non-faith of The Church of Jesus Christ of Latter-day Saints or LDS.

The school further has deemed that “full-time or part-time non-LDS faculty who are employed at BYU for one year or less may wear a beard, unless it is intended that they continue their employment with BYU for longer than one year.”

Since affiliate faculty, visiting scholars and cooperating professionals “are not university employees,” the rule says, “they are encouraged, but not required, to be clean shaven.”
