Job Rotation SHOULD be implemented for workflows involving access to high-level business data and/or operations, including handling of Personally Identifiable Information (PII) and data/operations sensitive to the organization.
Job Rotation is a workplace control that, much like separation of duties, helps mitigate insider threats by removing single points of compromise. Blindly putting trust in any one employee to perform critical tasks by themself puts a business in danger of fraud or misuse that may go undetected for a long time. Job rotation helps mitigate this risk by swapping out employees on a set schedule, putting the critical tasks in different hands. This increases the chances of misuse being detected and reported. Job rotation can also help foster a healthy work environment, as employees can offer feedback and advice to one another regarding their job performance on shared tasks.
Businesses hire their employees to perform specific, dedicated jobs. So, while it is important to ensure employees work within their skill sets and job descriptions, it doesn't hurt to rotate tasks between multiple employees per department.
As an example, consider a small local retail business. The retail business could implement job rotation and have the cashiers, stockers, and cleaners rotate jobs every other week to ensure that no one group is left in charge of the cash. If the business has any social media pages, management could put a different person in charge of running the company pages every month, disabling others’ accounts until it is their turn to run the pages. This will ensure that customer engagement is not left in the hands of one individual at all times.
