“ Can it be called an unreasonable or arbitrary regulation that requires an employing corporation to furnish to an employee, who after having served it for a time is discharged or voluntarily quits the service, a letter, signed by the superintendent or manager, setting forth the nature, character, and duration of the service rendered, and for what cause, if any, he left the service? It does not prevent the corporation from employing whom it pleases on any terms that may be agreed upon. ”
