We have very exhaustively dealt with the various demands made by the workmen, the minutes recording the discussion that c took place between the parties regarding the demands the conclusions arrived at therein as well as the final agreeme~ts entered into on different dates between the parties, a& they furnish the background, so to say, for the agreement under consideration Ex. A.5. It will be seen that originally in 1946 the payment was made as production or special bonus. Specific demand was made D by the Union on March 6, 194 7 to increase "production bonus". The Company did not agree to this request. On the other hand, Ex. C., the agreement, clearly shows that there would. be no increase in production bonus. But an additional amount was given as attendance bonus. In 1948 what was originally characterised as production bonus was termed "ex-gratia" payment of bonus. The U'.lion specifically desired in 1951 to substitute "ex- E gratia bonus" by "general bonus" an4 to abolish attendance bonus. The demand also was for general bonus to be paid at a tlat rate every quarter. For the first time the expression "general bonus.'' occurs in the demand made by the Union on May 15, 1951 and in the agreed minutes of October 3, 1951. The same was incorporated in the final agreement of November 22, 1951. The Union F made a demap.d on March 11, 1954 for increase in the rate of general bonus so as to provide an incentive to the employees. This was accepted and embodied finally in the agreement dated February 18, 1955. In Ex. B.5, the. Union made a specific demand for further increase of the rate of general bonus and wanted half the amount to be paid quarterly as at present and the balance at G the time of pooja. Though, the minutes of the discussion in respect of this demand shows that the Chairman of the Company wanted to alter what was given as incentive to greater efficiency in production to one on profit basis, the Union preferred the payment to be contmued as was being done on a fixed percentage basis. The. pattern of bonus paid sometimes called production bonus, later on called ex-gratia payment, but from 1951 called as general fl bonus, was being paid quarterly at a particular percentage based· on the salary excluding dearness allowance. Having this · background in mind, it is clear that what was being paid under Art. VI
