This is what they would call a pulse check and timing of its release isn't coincidental in my view. Often they are used in the corporate world to judge employees views on the culture and direction of the business. Usually at times of change to gauge the impact. They will be reviewing alongside last year and reading the tea leaves. They would know what they are likely to get back but it will deliver comparative quantitative data to analyse and present to the board.
But will it really lead to any major change though it will they bury it?
