Maria has adopted an adversarial style relationship with her stationery supplier.

An adversarial relationship is characterized by a competitive, often zero-sum approach where:

Minimal sharing of information (A): In adversarial settings, there is limited transparency as each party prioritizes its interests.

Use of power to seek the best possible deal (D): Power dynamics are leveraged to gain favorable terms, often at the expense of the other party.

This style typically lacks collaboration and mutual commitment, focusing instead on short-term gains rather than building a partnership, as described in CIPS resources on adversarial relationships.
