If the strike was caused by the employer's failure to comply with state or federal laws governing wages, hours, or working conditions, the claimant is not disqualified as a result of the strike. However, to establish the strike was caused by unlawful practices, the issue of an unfair labor practice must be one of the grievances still subject to negotiation at the time the strike occurs. The making of such an allegation after the strike begins will not enable workers to claim that such a violation was the initiating factor in the strike.
