The Employees screen shows all employees. Users can request the following changes for an employee:

• Salary - Requests a change to the employee's salary. This functionality uses an approval task to review and approve the change and a customized task details page.
• Job - Requests a change to the employee's job. This functionality uses an approval task to review and approve the change and a standard task details page.
• Appraisal - Begins the process of an employee's appraisal. This functionality uses a workflow with action tasks for the employee, the employee's manager, and, if applicable, a VP.
• Laptop - Requests the purchase of a new laptop for the employee. This functionality uses a workflow with an approval task and an action task. The workflow is programmatically completed when the laptop is delivered.

Clicking on the title of each workflow instance gives the workflow participant (in the OPERATIONS department) access to perform further actions with the workflow, including checking workflow activities, variables, parameters, and history.
