On the legal issues, I think DH has been sailing very close to the wind for a long time. A lot of the comments he has made about the company and its senior management are defamatory. Time will tell whether the company has been waiting to choose the right moment to do anything about this.
As for next week's meeting, I suspect BASSA will not allow any cameras into the meeting. Whatever happens, I'm sure DH will issue a rousing account of the "electric" atmosphere, 100% support for a strike etc.
