“There are several facts in the record that speak to whether plaintiff was fired because of his religious practice or his refusal to trim his beard,” U.S. District Judge Julie R. Rubin wrote. “The weight and credibility of those facts are best determined by a fact finder. Importantly, plaintiff raises the fact that Walden never prepared to utilize, or actually utilized, the N95 masks that served as the basis for requiring plaintiff to trim his beard to one-quarter inch. The fact finder must evaluate the credibility of Walden’s claims that it had a legitimate purpose for terminating plaintiff.”
