Package bargaining is a strategy used by negotiators to propose a set of interrelated issues that can be negotiated as a package. These interrelated issues are also known as bundles, and can include a group of proposals, offers, or concessions. The term "package bargaining" can be interchangeable with other terms such as "multi-issue bargaining," "holistic bargaining," or "bundling strategies." The use of package bargaining can often lead to more efficient and effective negotiations because it enables both parties to consider the entirety of an agreement instead of just negotiating individual issues. As such, this strategy can be found in a variety of fields, including politics, business, and even in labor-management negotiations.
