Teams behaviour T5

Mastering Conflict

Artificial harmony hides real issues and weakens decisions. Make it safe to disagree about ideas, not people, then decide clearly and commit together.

What this behaviour looks like

Disagree and commit

A leader sets norms for respectful challenge, invites different views and keeps disagreement on ideas and evidence, not personalities. Once views are heard, the leader decides, explains why and asks everyone to commit, so colleagues, pupils and families see one clear direction.

A practical example

Discussing a new marking policy

Artificial harmony“So we're all happy with the new marking policy? Great. Let's move on to the next item.”

Constructive challenge“Before we decide, what might we be missing, and who sees this differently? Thank you, that workload point matters. I'll decide by Friday and explain my reasons, including how I have weighed workload. Then I'm asking all of us to commit.”

Invite challenge

Ask who sees the marking policy differently before deciding.

Focus on ideas

Thank the colleague and weigh the workload point on its merits.

Decide and commit

Decide by Friday, explain why, then ask everyone to commit.

Now try it at your next decision meeting.

Before sharing your own view, ask one question that invites challenge and respond without defending. Then close by stating the decision, the reasons and what you need everyone to commit to.

Worked example at a glance

Settling a playground supervision dispute

The challengePlayground incidents rose from 11 to 23 in one half term. Teachers propose fixed zones, lunchtime supervisors say adults need to move with pupils, and frustration is becoming personal outside meetings.

What the leader doesThe headteacher brings a real playground map and incident chronology, hears lunchtime supervisors before teachers frame the problem, stops dismissive language, makes decision rights clear and agrees a safe ten-day pilot.

What success looks likeBy day 30 every duty colleague should follow the agreed routines and the ten-day pilot should run safely; by day 60 incidents should fall from 23; by day 90 staff and pupils should find supervision clearer and safer.
