I agree with 101917.
However, as the poster noted, this has not yet been properly challenged in UK Courts. It only takes one person to challenge any "deal" done, and the 300 vs 3000 becomes irrelevant.
The "majority" may well end up being shunted further down the seniority lists - although the Courts might also rule those lists to be unlawful.
Human Factor's questions need to be sorted out in the law courts. Until they are, I can't give a definitive response to those questions.
Interesting times.
