While the intensity of training among the medium qualified employees was especially high, this is mostly due to the fact that this group constitutes the largest group of employees in Germany.
In 2012 it was 1639, with 1415 active workers, 152 medium-level employees and 35 Cuban doctors.
Enterprise size parameters was defined using unified size bands: small (5 to 19 employees), medium (20 to 99 employees), and large (more than 99 employees) see Table 4.
We differentiate hospitals by size using the following categories: small hospitals have between 1 and 20 employees, medium hospitals have between 20 and 100 employees, and large hospitals have over 100 employees.
We define three types of plants according to its size: small plants are those with less than 20 employees, medium establishments are those with a number of workers between 20 and 99, and large establishments are those with 100 or more employees.
Workplaces were categorised as small (up to 50 employees), medium (1 250 employees) or large (more than 250 employees), and by location (city centre or suburban) and type of business.
Socioeconomic status (SES) by occupation includes the six categories on the labour market: higher non-manual employees, medium level non-manual employees, low level non-manual employees, skilled manual workers and unskilled manual workers as well as self-employed/farmers.
The study companies were selected by random, probabilistic, two-stage (primary sampling unit companies and subunit worker) sampling, stratified by department (Boyacá and Cundinamarca) and company size (small: under 50 employees, medium: 50 to 99 employees, and large: 100 or more employees) in conglomerates (companies) with proportional allocation.
This categorization is based on the recommendation of the European commission to classify large companies as having 250 or more employees, medium-sized companies as having between 50 and 249 employees and small companies as having between 49 and 10 employees [ 18].
