Gender Pay Gap Reporting

With the goal of promoting greater gender diversity, the UK Government requires all employers with 250 or more employees to disclose their gender pay gap on an annual basis.

Mean vs. Median

  • Mean is the same thing as average: the sum of all values divided by the total number of values.
  • Median is the middle point of the data set: half the values will be less than the median, and half will be above.

Proportion of males and females in each pay quartile

The workforce is portioned into evenly sized quartiles based on ranking of all full-pay individuals from highest to lowest by hourly rate of pay. The following charts show the number of full-pay male and females in each quartile as a percentage of the total in the quartile.

  • There are no differences in pay rates for different genders occupying equivalent roles
  • Employees that work unsociable night shift hours are generally male, and this attracts a higher pay rate 
  • VV UK are actively seeking to address the discrepancy in male/female employees in the upper middle and upper quartile pay bands
  • We have a  pay gap relating to bonus payments. The majority of bonus payments in our business are sales commissions and currently a majority of our sales team is male.

I can confirm the data reported is accurate - Rachel Hawkins, HR Director.
