8. On the assumption that their Honours were right in treating the respondent's "sick pay" as an independent benefit which the respondent had secured to himself by past services and not otherwise there might be something to be said for the final conclusion which they reached. But, in our view, the first step which they took was erroneous. It may be true, to some extent at least, that the amount of "sick pay", or to be more precise "sick leave", to which an employee of the Board will become entitled will depend to some extent upon the length of his service. But it is quite wrong to say without qualification that if he is permitted to be absent on leave, or on sick leave, on "full pay", and so relieved of the obligation to perform his duties, the pay which he receives cannot, therefore, be regarded as wages or salary. Generally, no doubt, the performance of services is a condition precedent to the right to wages and it is for this reason that it is said, as no doubt their Honours were aware, that a servant who has been wrongfully dismissed cannot wait till the determination of the period for which he was hired and then sue for the whole of his wages. But this, as Jordan C.J. pointed out in Watson v. Automatic Fire Sprinklers Pty. Ltd. (1946) 46 SR (NSW) 336; 63 WN 107 , is not universally true. It is, as he says, "correct only in cases in which, by the contract of employment, the actual doing of work is made a condition precedent to the right of wages" (1946) 46 SR (NSW), at p 342; 63 WN, at p 110 . See also per Latham C.J. and Dixon J. (as he then was) in Automatic Fire Sprinklers Pty. Ltd. v. Watson (1946) 72 CLR, at pp 452, 465 where the same view is expressed in less general terms. The circumstances of that case were, however, exceptional and for present purposes the decision is not of importance except to illustrate that wages, in every sense of the word, may become payable according to the terms of a contract of employment even though the employee is not called upon to, and does not, in fact, render service. Perhaps, it should also be said that in the present case we are not so much concerned with the fact that an arrangement of such a character may sometimes be found as one of the incidents of a contract of service; we are concerned with a contract pursuant to which, generally speaking, the employee was bound to work for his wages. But the contract contemplates the possibility that circumstances of a defined character may arise and prevent the employee from performing his duties. In those circumstances he is to be entitled to absent himself on sick leave and, subject to specified limits, to receive "full pay" whilst on leave. In our view the respondent's contract says no more and no less than that, if he becomes unable by reason of sickness or other specified causes to perform his ordinary duties, nevertheless his right to "full pay" or, in other words, his ordinary wages, shall continue to be payable, subject to the limits specified, during the period of his absence. If, therefore, the claim be made, as it was, that the respondent lost the whole of his wages between the date of the accident and the date of trial then the appellant was entitled to answer it by showing that for a period of 178 days he received his full wages.
