Final answer:
It is true(a) that in collective bargaining, both parties must negotiate in good faith even if they do not ultimately reach an agreement. This is a legal requirement to maintain a fair negotiation process.
Step-by-step explanation:
If a subject of collective bargaining is permissible, it is true(a) that both parties are required to negotiate in good faith, even though an agreement may not be reached. The concept of good faith negotiation is central to the labor relations process and is legally mandated in many jurisdictions. This means that both the employer and the union must be open to considering each other's proposals and must make a genuine effort to reach an agreement. However, this does not ensure that an agreement will be reached, as situations can arise where the parties fundamentally disagree or where reaching an accord is not possible due to irreconcilable differences.
