The segmentation of the workforce into primary and secondary sectors. The primary sector is the core workforce, most likely to progress and develop themselves and the business. The secondary sector is usually lower skilled, lower paid, and less likely to move up the ranks of the business.
In general labourers within the primary sector are usually the ones with good job roles, good salary, job security and status, with the opportunity to get promoted. Whereas workers in the secondary sector are most likely to have less advantaged jobs or in other words, less privileged jobs and most likely to make a low minimum income wage, with less job security and very poor working conditions.
