The implementation of work activities using the outsourcing system in the modern era has
the purpose to save the company's costs in providing wages to workers so that they focus
on business processes in a company. The problem raised in this study relates to
violations of work conditions and labor rights that should be accepted by outsourcing
workers /laborers in electrical installation companies, classification of the separation of
core business types of work, or activities that are not related to the production process in
a company using outsourcing systems. This is regulated in article 65 section (2) of Act
Number 13 of 2003 concerning Manpower which explains that the classification of core
business work and supporting activities (non-core business) have no further regulations
that control specifically the separation of core business activities and non core business.
