Question

Quizplus · Accepted Answer

The standard employment relationship (SER) is based on three pillars: full-time work, continuous employment, and the employer-employee relationship. Precarious work, such as part-time work, undermines the standardized working time pillar of the SER, as employees do not have stable and continuous work hours. None of the other options directly threaten the three pillars of the SER.
