Before this, contractual work was limited to jobs that were not related to the main production in the enterprises; it consists mainly of jobs in the periphery, such as janitorial, security, messengerial work and the likes.
Bago ito, ang kontraktwal na trabaho ay limitado lamang sa mga gawain na hindi direktang kaugnay ng pangunahing trabaho sa kompanya, gaya ng janitorial, security, messengerial work at iba pa.
