            throw new NotFoundException(__('A Company is required'));

        }

        

        $this->loadModel('Companies');

                $this->Flash->success(__('The employee has been added successfully'));

                return $this->redirect(['action' => 'index']);

            } else {

                $this->Flash->error(__('Unable to add the employee, please try again'));

            }

        }

        

         

        $departments = $this->Companies->Departments->find('list'); // Here, Want to get only Departments lists of that company passed through $companyId
