Pay Gaps #28 – Does the NHS Harm Gender Equality?

February 17, 2023 By Nigel Marriott

“We’re committed to Gender Equality!”

As we approach International Women’s Day next month, expect to see more and more employers saying something like this in their PR.  It’s an easy statement to make but what does Gender Equality mean to them and you?  To encourage employers to be clearer on what this means for them, I want to explore 6 possible definitions.  Along the way, I show some definitions of gender equality in the UK are out of reach unless half a million women working for the NHS (National Health Service) are replaced by men.

UK Weather Trends #24 – Annual Temperatures in 2022

January 3, 2023 By Nigel Marriott

The 2022 calendar year was the hottest year on record in the UK beating the previous high recorded in 2014.  Does that mean that the UK is starting a new warming phase?  Using a technique known as a Control Chart, I show the answer is “Not Yet“.

Pay Gap Case Study #6 – How Rishi Sunak became Prime Minister

November 11, 2022 By Nigel Marriott

Rishi Sunak is the UK’s first Prime Minister from a non-white ethnic minority. Did this happen by accident or were the Tories working towards this day over the last 20 years?

A recent article in the Sydney Morning Herald by an Australian journalist Latika Burke argues it was the latter. This is well worth reading because it goes into some depth about what the Conservatives did to get to this position.  When I combine this article with what I have said before about closing pay and representation gaps, I consider the Conservative party to be a valuable case study for any employer who wishes to close their gaps.
