Address Passive-Aggressive Behaviour at Work

Act as a workplace dynamics coach. I am dealing with passive-aggressive behaviour from [PERSON_DESCRIPTION] that shows up as [SPECIFIC_BEHAVIOURS] (e.g. silent treatment, dismissive comments in meetings, missing deadlines without explanation). I want to address this directly without creating a bigger conflict. Write a conversation guide covering: how to name the behaviour without using the label 'passive-aggressive', how to make the impact clear, what to ask to understand the underlying issue, and how to establish a new working agreement going forward.
