The gap between the top-paid and least-paid employees of the 39 largest companies in Switzerland remains high, despite a 2013 vote against excessive executive pay. According to Switzerland's largest trade union, Unia, in 2017 the average ratio between top and bottom in these companies was 1:143. The chief executive of Switzerland’s leading bank UBS took home the highest salary, CHF14.2 million ($14.2 million).

The bosses of Novartis, Roche and ABB all have annual incomes more than 200 times higher than their lowest paid employee. Collectively, CEOs at the top 39 companies earned CHF172 million – almost CHF1 billion if other types of remuneration are included in the calculation.
