The HR team wants to display each employee alongside the name of the person they report to.
The employees table contains each employee's identifier (emp_id), name (name), and manager's identifier (manager_id). Managers are also employees in the same table.
Prepare a report showing every employee and their manager's name. Employees without a manager, such as the head of the organization, must still appear with NULL in the manager column.
Ordering: Sort by emp_id in ascending order.
