I expect it will be very difficult indeed to find one single instruction or inducement which is clear cut. However "do the right thing" in the context of a longstanding relationship where GCC was a member of Stonewall's WEI/Champion scheme (?) rather changes things.
The schemes are structured around a series of questions and points are awarded for correct answers. The more points the higher the total score and the higher the organisation ranks on a national scale. From what I can tell loads of organisations wanted to be in the WEI100 completely ignoring the fact that, well, maybe 500 organisations had the same idea... 🤔
That is the sort of relationship where you want to please the person scoring you and avoid upsetting them in case they mark you down.
The scheme is also carefully constructed with a very specific "choice architecture" (cf behavioural economics). So although the schemes are - signed up to voluntarily - choices are somewhat manipulated using behavioural techniques which are difficult to row back on - Cialdini's principles of persuasion.
In this sense, the "nudges" being used by Stonewall and others as part of the choice architecture of the schemes could be considered "inducements". It will need someone cleverer than me to argue it tho!
I watched a film of a young dr who did a presentation on how he "Rainbow Badged " his Trust - he was given time off clinical duties and extra pay to do it. It was fascinating because the way the scheme is constructed, the tick box mentaility, just takes over. He seems like a really lovely and bright chap - but in following this scheme it put blinkers on him and seemed to terminate any critical thought!
Here it is if anyone is interested:
