Over a quarter of Swiss employees are stressed to critical levels. In 2018 Health Promotion Switzerland (Gesundheitsförderung Schweiz / Promotion Santé Suisse) reported that the productivity loss caused by the critical stress levels costs CHF6.5 billion/year (USD 6.6 billion/year), or a full percent of Switzerland's GDP. Absenteeism (5.5%) and Presenteeism (15.6%) among the 16-24-year-old population are at 21.1%. Absenteeism is discussed much more often, even though absenteeism is three times higher.
The Universities of Applied Sciences in Bern and Zurich conducted a three-year (2014-2016) study and discovered, that a quarter of all Swiss employees are stressed and exhausted. It's important to note that absenteeism is only the tip of the iceberg, on-the-job inefficiencies caused by high-stress cost twice as much as absenteeism costs.
