of their service conditions, to discharge their duties for six days in a week and, therefore, it was open to the municipal authorities, looking to the exigencies and pressure of work, to give some additional concession to only those office staff members who would have been permitted not to come for work on any Saturdays. Therefore, all that we can lay down in the present proceedings is to the effect that if the appellants, at the relevant time at which they claim to have earned the right to enjoy holidays falling on Saturdays were made to work while their colleagues similarly situated like them, working in the offices of the Municipal Committees were given the benefit of such holidays and when there were no bye-laws requiring the employees to work for 6 days in a week, then they would be entitled to be given monetary compensation for the working Saturdays by grant of extra wages for each of the working Saturdays on which they are shown to have discharged their duties.” (emphasis applied)”
