OP.... In response to your post...
There have been accusations that the secret filming of women at work in the club was exploitative.
Bloody right it is. How dare anybody film me without my knowledge at all and especially when I am potentially naked in a private dance. How dare they.
It was an investigation into whether the club was breaching the licence agreement and to do that they needed evidence.
No "they" didn't. "They" didn't need anything. They took it upon themselves for their own self purpose to film us like pitiful rescue animals get filmed in crates.
This they found through the filming which is a standard method for undercover investigation.
By an official authority perhaps. Not some self appointed Captain-Save-A-Ho troup.
The issue here is were the women coerced into sexaul contact by the club or were they individuals acting on their own initiative.
Absolutely individuals acting on their own initiative. Because we are all self employed, and if we see any girl doing "extras" she's reported by the rest of us and sacked. Immediately. Because if you want to be a prostitute, fine. But don't come in to a dance club because the hourly rate is higher, and perform your services in there. It's not what we do. It's bloody hard to be a successful dancer. If you're not good enough to be a dancer, get out of our club, don't piggyback off our hourly rate then just grab people's dicks for an hour because that's all you can do. It's a real skill to entertain someone at the huge prices we charge and for them to come back for more, you need to be very skilled to do it, and I'm damn proud of us.
Either way the club as the managers of the work environment were ultimately responsible. And this is why they shouldn't have had their licence renewed as the evidence showed they couldn't manage the club properly.
I don't know what the "evidence" specifically showed. But if the management knew there was prostitution going on and welcomed it, yes, it is no way representative of any club I've encountered in a decade, and should be closed immediately.
The fact that they apparently sacked some women doesn't mean they are innocent and the women guilty.
Oh the women are guilty, trust me. No one touched me. Ever. Dancers are in full control of the situation. If any of these women try and claim "oh I couldn't help it" he just kept persistently touching me, it's a lie. They allowed it. If someone walks up to you and grabs your ass, you don't stand there and go "oh no, there's nothing I can do about this" 
If my doormen saw anyone try and touch me, they'd be out without their feet touching the floor. Zero tolerance.
But have to say would have liked to see something from campaigners about making contact with those sacked to here there side of the story.
This will be a tricky one. Because if they've been doing extras in a club and been sacked for it, are they going to admit it was all down to them, or is it easier to attempt to save a bit of face and say "oh that big bad club made me".
And if necessary putting them in touch with a union. (Isn't it the GMB who says they represent women in "sex work"?)
Couldn't tell you. My whole ten+ years of actual experience in the industry, I've never had any reason to need a union or even know if one existed.
OP, you ask some very interesting points.
