You don’t! At least not in the sense that I’m aware of the JADE thing:

JADE is nothing that is a strong work proven topic but came from social media to handle narcissistic people as a peer group.

Your reactions are hostility and rejection based and how I understand you it’s your nerves that you want to preserve.

For this in a professional work place there are multiple ways to deal with and even all of them at the same time, just from the top of my head:

• Always go over your manager, make it his problem. "Dispatcher causes work for me by raising false claims/redundant questions - please resolve with their manager"
• I’d call it business ghosting: answer and questions raised but but don’t go into any depth. "Correct, phone was not working due to no wifi."
• Work on yourself to detach your emotional connection: this is the toughest but also the most valuable one. It’s a fucking dispatcher who has his own problems and no other way to handle them then to try to use his environment as catalyst. My personal route is the framing “poor fucker, needs his routine and world to accept himself”. But also “this seems to be the only way he can feel important in front of himself” would work for me. Usually when I take pity with people I can’t get angry anymore about their behaviors.
• Figure out what the true impact on your work performance is and handle that separately from the emotional connection. It’s absolutely normal to be annoyed and angry by the behavior you’ve described - detachment of impact and emotion can be a way forward.

Hope this helps a bit!

If ignore any request outside his authority.

I would also start making IT tickets every time your device stops you from working. Maybe you have a unique bad device or there is a systematic problem with the topping and nothing will change untill enough people complain about it.

I don’t think JADE is necessarily the right approach.

I don’t really understand the situation you’re trying to describe.

he likes to ask per chat if the smartphone works ok

What does this mean? Why is he asking if he’s just going to say “the smartphone works” regardless of your response?

Your suggested response is defensive and argumentative by the way, particularly so.

I would handle this by just playing along. If he asks if the phone is working just say “yes”. If a problem with communication arises and you use your best judgement, which later pisses him off, just explain what’s happened and ask what he would like you to do next time.

You don’t actually have to to what he says, just make him feel like you’re acquiescing to his authority.

I can’t help you, it just sucks. You’re not the only one though, JADE is dreamt up by utterly deranged boomers who don’t have the brain cells to comprehend the obvious and self-evident difference between an explanation and an apology, they are wholly unhinged and often lack basic reading comprehension and literacy, it’s a shame there hasn’t been more wars and pandemics to thin out their ranks so we don’t have to deal with them.
