UK Weather Tracker #55 – August 2021

September 5, 2021 By Nigel Marriott

The weather in the UK in August 2021 was totally and utterly unremarkable.  Overall, Scotland & Northern Ireland had a hot summer and whilst England was above average, it was not notably so.

Pay Gap Trends #4 – Did the UK gender pay gap narrow in 2020?

September 5, 2021 By Nigel Marriott

This article was last updated using data submitted as of 4th September 2021.

In February 2021, the EHRC confirmed that all employers with a headcount of 250 employees or more would have to submit their gender pay gaps based on the 2020 snapshot date.  Due to the lateness of this confirmation, they also stated that no enforcement action would be taken prior to the end of September 2021.  As result, fewer employers than expected have reported 2020 data so far so I have used two methods of imputation to estimate that the median gender pay gap among these employers narrowed by 0.2 to 0.3 pence in the pound in 2020.

Pay Gaps #23A – How long will it take to close your pay gap?

August 9, 2021 By Nigel Marriott

Five months ago, I introduced the gender swap number as a superior statistic to the median gender pay gap.  Feedback from clients and others since then has confirmed my hope they would find it more intuitive to use and interpret.  This encouraged me to call on Parliament to amend the UK gender pay gap legislation so that swap numbers could be published for employers with 250 or more employees.  I now want to build on this by showing a couple of simple calculations that can turn a swap number into an estimate of how long it will take an employer to close its pay gap.

COVID19 Summary #1 – Is the UK an outlier internationally?

July 12, 2021 By Nigel Marriott

The COVID19 pandemic is not yet over but with vaccinations starting to ramp up worldwide, an end may be in sight.  At that point, an in-depth comparison of countries is likely to take place.  To get ahead of that debate with the respect to the UK, I have been comparing the UK’s COVID19 statistics with a number of countries to see how much of an outlier the UK has been.

Pay Gaps #22 – My 7 + 5 recommendations for amending UK pay gap legislation

June 30, 2021 By Nigel Marriott

When gender pay gap reporting was introduced by the government for the 2017 snapshot date for all employers with a headcount of 250 or more, it was made clear they would evaluate how the legislation had worked after 5 years.  We are now in the 5th year of pay gap reporting and I would like to submit to the government 7 recommendations to improve the way employers’ data is reported and 5 recommendations to improve the data used in the calculations and to reduce various distortions.

June 6, 2021 By Nigel Marriott

Spring 2021 was colder and sunnier than usual in the UK but otherwise unremarkable.  However the 3 months of spring were anything but unremarkable.

UK Weather Tracker #52 – May 2021

June 6, 2021 By Nigel Marriott

April 2021 laid down the challenge for unusual weather in the UK and May 2o21 failed to rise to it.  It was wetter and frostier than normal and generally colder and darker than usual but not to the extent that we could say May was unusual.

Pay Gap Case Study #5 – Why Ryanair’s pay gap report is my favourite

May 28, 2021 By Nigel Marriott

Ryanair has the largest (verified) gender pay gap of any employer in the UK, they didn’t bother to report their 2019 pay gap, they are leaving their 2020 pay gap reporting to the last minute, it’s pay gap narrative is only 1 page, they incorrectly use pie charts to represent the pay gap and they have a dodgy bar chart the Liberal Democrats would be proud of!  But apart from all that, Ryanair’s gender pay gap report is a shining example that all other employers could learn from.  Out of the hundred plus pay gap narratives I have read so far, Ryanair’s is my favourite.
