15. The premise upon which this part of the argument for the association depends is that if the making of agreements of the kind now under consideration between employers and employees or their unions has become common, that is a sufficient reason for regarding a demand upon employers, who are unwilling to make a similar agreement, as an industrial matter. If the premise were to be accepted as correct, it may be doubted that the material placed before the Court has established facts which would warrant the conclusion for which the association contends. But, in my opinion, a consideration of what is involved in the subject matter of the agreements upon which reliance is placed shows that the premise ought not to be accepted. So far as appears from the material before the Court which deals with Australian conditions, what has occurred in regard to deducting subscriptions from wages and paying them to the union has been that some employers have assented, no doubt at the request of the unions concerned, to the making of such deductions from the wages or salary of any employee who requests and authorizes the employer to do so. There has not developed a system by which the making of the deductions is introduced as a term of the employment of each of the employees of those employers who have agreed to make the deductions. The practice is not applied to all employees nor to all who belong to a particular union. From the employer's point of view, there is not an obligation owed by the employer to each employee because he is an employee. The making of the deductions depends upon an authority given by an employee, who is free to withdraw the authority if he wishes to do so. The system should, therefore, be regarded, in my opinion, as pertaining primarily to the relationship between an employee and his own union, from which relationship arises the obligation which is discharged by the payment made to the union by the employer. In so far as the practice also involves any relationship between an employee and his employer, this is not, in my opinion, a relationship between the employer as employer and the employee as employee, but is one in which the employer acts as agent for an employee in the making of a payment at his request and on his behalf from money to which he has become entitled. I am of opinion, therefore, that having regard to the character of the practice which some employers have agreed to follow and to the character of the demand made in the present case, the fact that a considerable number of employers have so agreed cannot support a conclusion that the matter in dispute pertains to the relations of employers and employees. The undertaking by some employers of an obligation of a kind which is not, in my view, within the scope of the relationship of employer and employee cannot have the consequence that such an obligation may be imposed upon unwilling employers, upon the basis that their failure to assume the same obligation has given rise to an industrial dispute.
