What are 'side letters' in ILWU contracts?

Side letters in ILWU contracts refer to supplemental agreements that address specific issues not covered in the main contract. These side letters serve as important tools for clarifying and expanding upon the terms outlined in the primary labor agreement.

For example, a side letter might provide additional details regarding particular working conditions, benefits, or procedures that the primary contract does not explicitly mention. This allows for more flexibility and adaptability within the labor-management relationship, ensuring both parties can respond to specific concerns or situations that arise over the course of the contract.

The nature of side letters is that they are generally formalized and recognized by both the union and the employer, which distinguishes them from casual or unofficial notes. The purpose of side letters is to refine and enhance the contract rather than to disregard or contradict the main agreement, nor do they constitute broad modifications to the core contract itself.
