Two experienced technicians are both valuable, but distrust, resentment, or constant conflict between them is affecting assignments, communication, or the rest of the crew.
Do not become the messenger between them
If each person only speaks through the supervisor, the leader can accidentally become the infrastructure keeping the conflict alive. Understand each side separately, but do not make permanent triangulation the solution.
At some point the shared work relationship has to be addressed.
Define the operational damage
Focus on missed handoffs, withheld information, duplicated work, arguments in front of the crew, refusal to support assignments, or the effect on junior technicians.
That keeps the problem grounded in behavior rather than deciding which personality is more likable.
Require professional cooperation, not friendship
People do not need to like each other. They do need to exchange necessary information, respect work boundaries, and execute the team's priorities.
Set the standard at professional function, not emotional reconciliation.
Avoid these traps
- Choosing a favorite and treating the other person as the problem.
- Reassigning work forever to keep them apart.
- Forcing a superficial apology without changing the operating behavior.
- Allowing junior technicians to inherit the conflict.
Useful language
What good looks like
Both technicians can remain strong individuals while the team regains predictable handoffs, communication, and professional standards.
