For each employee, you can determine what you want the employee to be able to see and do within the application. The default level of access for Personal and Payroll Information is no access. You can also grant access to a user to edit or view their information. If an employee's access is blocked, they will not be able to view or edit their Personal and Payroll Information.
Security can be broken down by different user types:
Application level security is typically a company or CPA user that has access to all employees or a logical sub-set within the company.
Employee Access security is user access to your own personal information as an individual employee.
