Labor Law is best defined, perhaps, as that body of law which is directed toward, and peculiar to, the various incidents of the employer-employee relationship, whether viewed individually or collectively.\u27 In this sense it includes all laws, such as those on workmen\u27s compensation, wages and hours and unemployment insurance, setting forth the rights and limitations of the individual employee as against the employer (directly or indirectly), as well as those concerned with union organizational activity and collective bargaining
