The 23 countries with the happiest and most loyal workers

Universum has released its annual Happiness Index, a measure of the happiness of workforces in countries around the world.

The employee branding firm surveyed more than 200,000 young professionals in 57 markets, making it one of the most in-depth rankings of its kind.

The research uses a scoring system that tracks three factors: Employee satisfaction, an employee's willingness to recommend a current employer, and an employee's likelihood to switch jobs in the near future.

The top 10 is dominated by countries in Western Europe and the European Union, with Scandinavian countries performing particularly well.

The United States and the United Kingdom didn't make the top 23, ranking 36th and 32nd respectively, but countries including Canada, Singapore, and Brazil all appeared higher up the list. Scroll on for the top 23.
