(1) This section applies while a collective agreement made under section 11A between the owner of the ship and the seafarers' bargaining unit for the ship is in force.
(2) So far as a work agreement applies to the seafarer while he or she is working on board the ship when it is used to engage in international trading, the work agreement is taken to include the terms and conditions of the collective agreement.
Note: It does not matter whether the work agreement was made before or after the collective agreement was made.
(3) However, a term or condition of the collective agreement that is included in the work agreement because of subsection (2) has no effect to the extent that it is less beneficial to the seafarer than another term or condition of the work agreement.
