Passive aggressive behaviour
People with passive-aggressive behaviour express their negative feelings subtly through their actions instead of handling them directly. This creates a separation between what they say and what they do.
For example, say someone proposes a plan at work. A person with passive-aggressive behaviour may oppose the plan, but instead of voicing their opinion, they say that they agree with it. Since they’re actually against the plan, however, they resist following it. They may purposely miss deadlines, turn up late to meetings, and undermine the plan in other ways
