We will study the two following themes: *Can employee motivation be increased by CSR? *What impact does CSR have on the work carried out by the employees? To answer these questions, we will carry out a field study (monography) of targeted companies (Insee database, company and sustainable development survey). We will attempt to match various data with answers to the survey. We will then be able to correlate company types, as set by the criteria used in the survey (sector, size, etc.)
