1. "The rule that an employer has an absolute right to discharge an at will employee must be tempered by the principle that where the employers motivation for the discharge is to contravene some substantial public policy principle, then the employer may be liable to the employee for damages occasioned by this discharge." Syl., Harless v. First National Bank, 162 W.Va. 116, 246 S.E.2d 270 (1978).
