Pay Gaps #21 – No employer has a gender & ethnicity pay gap! Let’s celebrate!

April 19, 2021 By Nigel Marriott

It’s April 2029 and the government is trumpeting the fact that no employer in the UK has a gender pay gap or ethnicity pay gap.  All employers say that their median woman’s hourly pay is the same as the median man’s hourly pay and their median white employee’s hourly pay is the same as their median non-white employee’s hourly pay.  Would you be joining in the celebrations?

Pay Gaps #20 – Abolish the Gender Pay Gap!

March 8, 2021 By Nigel Marriott

I call upon Parliament to abolish the Gender Pay Gap by requiring employers to report their Gender Swap Number instead.  When presented alongside an employer’s Gender Pay Fingerprint, the Gender Swap Number tells everyone how much work the employer needs to do to eliminate their gender pay gap and allows for a fairer comparison between employers.

Pay Gaps #19 – Employers should report their Ethnicity Pay Fingerprints

November 29, 2020 By Nigel Marriott

The UK government has promised to give their views and proposals for introducing Ethnicity Pay Gap (EPG) reporting by the end of 2020.  A year ago, I pointed out statistical, data & ethical issues with EPG and listed 5 possible ways EPG could be introduced but I have not yet focused on what employers should be reporting.  I have now concluded that Ethnicity Pay Fingerprints are vastly superior to Ethnicity Pay Gaps and my new recommendation is that all employers with 500 or more employees should be required to report their Ethnicity Pay Fingerprint (EPF) instead of their Ethnicity Pay Gap.  If EPF is widely adopted and found to be beneficial then I would recommend that reporting of other protected characteristics such as gender & disability should be reported using Pay Fingerprints instead of Pay Gaps.

Pay Gap Case Study #4 – What is the gender pay gap at Novartis UK?

September 15, 2020 By Nigel Marriott

Welcome to my next case study where I look at the 2019 pay gap figures of Novartis UK.  They caught my eye when they posted on LinkedIn the following statement.

“… our 2019 gender pay report which highlights that on average, women earn more than men across all of our UK sites and divisions…“

When I looked at the two legal entities that were required to report gender pay gaps, I saw that both reported pay gaps favouring men instead.  Something odd is going here and it’s a perfect case study to show why anyone who analyses pay gaps needs to pay more attention to a Bletchley Park codebreaker from world war 2 who introduced the world to Simpson’s Paradox.

Pay Gaps #17 – How to Spot an Incorrect Median Gender Pay Gap

August 11, 2020 By Nigel Marriott

I have a spotted an incorrect median gender pay gap published by a well known name in a certain industry.  They shall remain nameless for now since I am trying to get them to accept their error and publish a new gender pay gap report on their website.  I know they have made an error because their published data violates the laws of mathematics as I will explain in this blog.  All it takes to spot such an error is a simple calculation you can do in your head and an understanding what the median measures.

Pay Gaps #16 – Eliminate your gender pay gap by playing Blackjack!

August 2, 2020 By Nigel Marriott

Imagine where you work, the median women earns 33% less than the median man.  Although your workplace is gender balanced with 50:50 men:women, the pay gap exists because 1 in 4 of managers and 3 in 4 of the lowest paid admin staff are women.  How long will it take for the pay gap to disappear assuming that all future recruitment at all levels have 50:50 candidate pools with men and women equally likely to be appointed to the role?

Up to 25 years i.e. a generation

Pay Gap Trends #3 – Did the UK gender pay gap narrow in 2019?

June 14, 2020 By Nigel Marriott

On 24th March 2020, the UK government suspended enforcement of the gender pay gap reporting deadline of 5th April.  As of today, just over 50% of employers have reported their 2019 gender pay gap figures.  Despite this shortfall, I have used statistical imputation methods to calculate that the median gender pay gap narrowed in 2019 from 9.6 pence in the pound to 9.0-9.2 pence in the pound.

Pay Gap Trends #2 – My analysis of 7 sectors for Practical Law magazine

June 3, 2020 By Nigel Marriott

In April, I was asked to analyse the trends in UK gender pay gaps over the 3 years of mandatory reporting from 2017 to 2019 for Practical Law.  They were interested in 7 customised sectors and the links to these can be found in this post.

Pay Gap Data #3 – Where can I find gender pay gap data for 2019?

June 2, 2020 By Nigel Marriott

This post was updated on 3rd June 2020 with the latest data

Update 5/4/20 –  On 24th March, the government suspended enforcement of the deadline for reporting 2019 gender pay gaps due to the coronavirus outbreak.  As of now, Only 40% of employers have reported their 2019 data.  Employers are still required to report 2019 data but will not be punished for being late in doing so.

The government requires all organisations employing 250 or more employees to submit gender pay gap data.  All data is available to the public and can be found on the government’s gender pay gap website.  I have downloaded this data and created a spreadsheet tool to present the data in a more user-friendly and visual format.
