Third-party intervention should be avoided

A) when passions are high.
B) when the parties are at an impasse on the issues.
C) when progress is occurring or is likely to occur.
D) when the parties are unable to move the process beyond a particular sticking point.
E) Third party intervention should be avoided in all of the above situations.

Third-party intervention should be avoided when progress is occurring or is likely to occur. This is because third-party intervention may disrupt the progress and momentum of the negotiations or mediation. It is generally better for the parties to continue to make progress on their own without the involvement of a third party. In situations where progress is not being made or the parties are stuck on a particular issue, third-party intervention may be necessary to help move the process forward.
