The file should be called employees_controller.php, not employee_controller.php.

All controller files are named in the plural.

You can also learn about the naming of the tables and the conventions at http://cakeapp.com

I don't know if the question is still important, but the cakephp convention says that filenames for controllers must be in plural an without underscores, so your controller file should be named EmployeesController.php.
