Abstract
The conflict’s aim is to identify the relevant collective agreement when several govern the same employment relationship. Conflict doesn’t confer primacy to one agreement. Must be applicated the collective agreement which submits better or equivalent conditions than the others. Conflict allows both agreements to apply, regardless of whether they are concluded in labour sector or in firms. But this rule is restricted by the passing of a primacy rule which allows the company-level agreement to apply, instead of all others collective agreements, even if it doesn’t submit equivalent conditions. Primacy ousts conflict’s rule. Nevertheless, the thesis shows that, despite company-level agreement primacy, conflict still governs collective bargaining. Primacy doesn’t prevent labour sector bargaining.Furthermore, the research examines relations between different company-level agreements and reveals that conflicts still can be identified.
