Employee assignment data will give you all the information needed to see what the employees are doing at any given time. By providing them with this type of data, you can do some things that would otherwise be impossible to do. For example, you can perform a background check to see if an employee has been convicted of stealing from the company.
Additionally, if an employee leaves the company, you will want to be able to quickly add them to their job. This can help them get into their new job quickly, without having to go through a lot of paperwork. Employees should know how to easily get added to their job.
