Final answer:
Job sharing is the correct term for an arrangement where two or more employees share a job by dividing the standard total number of hours for the post between them.
Step-by-step explanation:
The environment where two or more employees share a job by dividing the standard total number of hours for the job between them is called job sharing. This arrangement allows individuals to work part-time hours while still fulfilling the responsibilities of one full-time position. In a job sharing setup, both parties have a consensus on dividing their work and often collaborate to ensure seamless operations.
This concept is distinct from other employment strategies such as job rationing, which typically involves limitations on the number of jobs or work hours available to reduce unemployment, and job security, which is related to the assurance of an individual's continued employment. Job posting refers to the process of advertising a job opening to potential candidates, while job flexing can involve flexible work arrangements, but does not specifically refer to two or more employees sharing one full-time job.
