This sector is characterised by the manufacture of products by companies with many employees and good internal communication is therefore essential, both at good times and bad times. At good times, it is sometimes impossible to keep pace with the work; there is often a lack of good employees, so a lot is asked of the existing staff. An important job for the management is to keep them satisfied and commited. Informed people are motivated people and motivated people make good products. Labour communication in the most elementary sense of the word.

The same applies to bad times. The communication between employees, Works Council and trade unions must then be meticulous and effective.
