Answer:
A job substitution
Step-by-step explanation:
A substitute is a person who takes over a job or position from another for a shorter period of time in his absence. The term is known from substitute teachers in the school, but also from substitute priests and substitute doctors who may be subordinate officials who temporarily take over for the superior.
Today, most temporary workers are used in industry and building/construction, where they give companies the opportunity for a faster adaptation to market conditions and thus help to strengthen the competitiveness of the business community.
