Final answer:
Tina is demonstrating the conflict management strategy of yielding, where she backs down when her ideas are challenged to avoid conflict, which is different from compromising, avoiding, or problem-solving.
Step-by-step explanation:
When Tina, known as a bit of a "softie," backs off from a challenge to her ideas, even when they are good, she is demonstrating a conflict management strategy known as yielding. Yielding is a strategy where a person gives in to the other side and lets go of their own stance or idea, often to avoid conflict or maintain harmony, rather than pursuing assertiveness or insisting on their perspective.
This stands in contrast to compromising, which involves both parties giving ground to come to a mutual agreement, or problem-solving, which seeks to find a solution beneficial to all through cooperation and collaboration. On the other hand, avoiding would mean that Tina is not engaging with the conflict at all—neither advocating for her idea nor yielding to others.
