Answer:
Job Rotation
Step-by-step explanation:
Based on the information provided within the question it seems that the technique that Matt is using is called Job Rotation. This business technique refers to the act of employees rotating between job roles within the same company and taking all the responsibilities that are associated with that new role. Which is exactly what is happening in this scenario since Chet is switching to the ownership position within the business until Matt gets back, then they would rotate back.
