A clear majority of the companies surveyed that have a whistleblowing system introduced it after 2000. The British companies surveyed have been using this tool for some time (see country charts). The statistical analysis shows that this is mainly attributable to large companies. In Germany, France and Switzerland, too, the proportion of SMEs that did not set up a whistleblowing system until after 2000 is higher than that of large companies.
The in-depth statistical analyses show that international and successful companies introduced a whistleblowing system earlier on. The companies defined as successful are those which, measured by their sales development, have grown over the last two years and also expect growth for the coming 12 months.
