Negotiation styles, like being competitive or working together, have good and not-so-good sides.
If you're competitive, you focus on your goals and might win quickly, but it could strain relationships. If you collaborate, you aim for everyone to win, which is great for long-term relationships, but sometimes it's hard to be assertive.
Compromising finds middle ground, keeping relationships, but sometimes you give up your goals. Avoiding conflicts can keep relationships safe but might miss good chances.
Accommodating means caring about others, which is nice but might mean you get taken advantage of. It's good to pick the right style for each situation to be successful and keep good relationships.
