The analysis inadvertently also created a list of the top 50 CEOs, which included bosses from a variety of different sectors.
The findings showed that Sky Bet (Sky Betting and Gaming) ranked 21st out of the 50 top places to work in the UK, with company and CEO Steve Birch receiving an approval rating of 97%.
Above SkyBet were companies RSM, ARM and the Office for National Statistics, which had the same approval rating but finished in places 20,19 and 18 respectively.
Top of the list was the American finance company, BlackRock. Its CEO Laurence D. Fink had an approval rating of 99%.
Similar ratings were also given to Microsoft CEO Satya Nadella, and SoftCat CEO Graeme Watt, which were the only other companies to gain a 99% approval rating.
On the opposite end of the list was Schuh Limited, which ranked 50th despite having an approval rating of 93%.
As quoted by the Daily Mail, Glassdoor CEO Christian Sutherland-Wong, said: “Over the past year, company leaders around the world faced unprecedented challenges to support employees during the Covid-19 crisis.
“Now, the employees have spoken and it's clear these CEOs excelled and found new ways to support their people when the world of work flipped upside down.
“Through a challenging year, it's inspiring to see top CEOs who, according to their employees, adapted to change, redefined visions and led with transparency while putting the health and safety of employees first."
Given the wide-ranging nature of the industries covered, the Sky Betting & Gaming CEO's inclusion is a testament to the gambling industry.
