Situation of Facts: The negotiation of a collective agreement can become difficult due to the importance for both parties in making decisions about aspects that affect unionized workers. The signed agreement becomes law between the parties. The Roca Dura Union managed to negotiate in its collective agreement a clause that stipulates that the Employer who collects the insurance premiums for occupational accidents "will pay the unionized workers their wages no later than the 1st of each month." Due to the economic crisis, the Employer has begun to pay on the fifth of the following month because that way he keeps the money in the bank for longer and obtains more interest that helps alleviate the economic crisis. The Unin Roca Dura is demanding that the Employer comply with what has been negotiated. The Employer argues that this is an internal problem and that the Union cannot intervene in it, since the workers are getting paid every month without any problem. 1.
