Pay Gap Trends #6 – Are we there yet?

May 10, 2023 By Nigel Marriott

Has 6 years of mandatory gender pay gap reporting (GPGR) made a dent in the UK’s gender pay gap?  According to a recent BBC article, not one bit at all.  Unfortunately, too many people on social media have been taken in by this misleading article and I will be submitting a formal complaint to the BBC soon to get it amended.  I rebutted this at the time with this LinkedIn post and I will now expand on that here to show what the true trend is and whether or not mandatory pay gap reporting has had an impact.

UK Weather Tracker #74 – March 2023

April 3, 2023 By Nigel Marriott

As we move from February to March, it normally gets warmer and brighter in the UK.  Unusually, March 2023 was colder than February, it didn’t brighten and it was wetter than normal.  However the abnormality index says this is just typical British weather!

6 Nations History #3 – The men’s story so far in 2023

March 24, 2023 By Nigel Marriott

The 2023 Six Nations (Men’s) ended with Ireland beating England to win their 3rd 6 Nations Grand Slam in the last 15 years.  France ran them close and Scotland recorded their 1st top 3 placing since 2018.  England & Wales disappointed their fans whilst Italy have some grounds for optimism despite their wooden spoon.

Pay Gap Case Study #7 – Does the Department for Work & Pensions have a Gender Pay Gap?

March 5, 2023 By Nigel Marriott

The Department for Work & Pensions (DWP) says for every £1 paid to the median man in March 2022, the median woman was also paid £1.  In other words, their 2022 median gender pay gap using hourly pay was 0%.  However, their Gender Swap Number per 1,000 employees for this date was +26 which immediately raises the question “Have the DWP made an error in their calculations like Cleveland Police did in 2017?”  This was my first reaction which seems remarkable for an employer with 91,006 full pay relevant employees on a public sector pay scale and the largest pool of statisticians of any government department.

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.
