Hello my name is ***** ***** I will help you.
Was there a reason this person was filming please?
What is it you want to achieve ?
Does he have a directors agreement?
Does the company have a policy about what misconduct is?
Does the company have a constitution or other rules?
Is it illegal, no. Otherwise people wouldn't be able to video anywhere without permission. You have groups who catch police, tv cameras who catch minsters etc.
However it could be serious misconduct yes. It is quite wrong to film a meeting in secret and then post it.
Can I clairfy anything for you about this today please?
