Leaders are ambassadors of the shared values and people watch whether their actions match their words. The leader spends time and attention on what they say matters (the calendar is the clearest signal), watches their language because words shape how people think about the work, asks purposeful questions daily that point attention to the values and priorities, and seeks feedback on how their behaviour affects others, since leaders cannot see themselves as others do and behavioural integrity depends on knowing.
