The binding legal principles established are: (1) When religion is the reason an employee cannot comply with a work requirement, and the employee is dismissed for non-compliance, the religion is the dominant and proximate cause of dismissal, not the mere refusal to work. (2) The test for inherent job requirements is a strict proportionality enquiry requiring: (a) rational connection to job performance; (b) genuine good faith belief in necessity; (c) reasonable necessity for accomplishing the purpose; and (d) proof that accommodation is impossible without undue hardship or insurmountable operational difficulty. (3) Employers bear the evidentiary burden of proving undue hardship from accommodation. (4) Employers have an affirmative duty to reasonably accommodate religious practices through modification or adjustment of jobs or working environment, not merely consider employee suggestions. (5) Employment practices penalizing employees for practicing religion constitute invasions of dignity as they demonstrate the religion is not worthy of protection and force choices between conscience and livelihood. (6) Courts may take judicial notice of notorious religious tenets from authoritative sources. (7) Constitutional protection of religion extends to voluntary practices subjectively central to individual religious identity, not only objectively mandatory tenets. (8) Legitimate commercial rationale alone is insufficient to justify religious discrimination; strict scrutiny applies to the inherent requirement defense.
