The Party's report also called attention to the prevalence of a petty bourgeois attitude among many families of workers, employees, and servicemen that keeps their members from accepting employment. To facilitate the employment of women, the Party urged more widespread provision of amenities, such as nurseries and dining halls, that would free them from household duties. Meaningful information on labor productivity is not available because statistics on this subject have not been published and because essential details of the methods used in calculating the percentage rates of increase in productivity that appear from time to time in official public statements are not sufficiently known. Based on physical output and labor data, Western observers believe that the published data overstate the actual advance achieved. According to the Politburo report, productivity in industry rose 2.2 times between 1950 and 1968, and this growth accounted for 60 percent of the increase in industrial production during that period. In agriculture 67 percent of the increase in output during those years was attributed to the growth of productivity. These figures indicate a slightly faster advance in agricultural productivity, but in absolute terms productivity in agriculture has been very much lower than in industry. During the Third Five-Year Plan (1961-65) labor productivity reportedly rose by an annual average of 2.1 percent in industry, 4.6 percent in construction, and 2.7 percent in automotive transport. Data for the years after 1965 had not been published by mid-1970 except for official statements that the planned levels had not been reached. The lag of productivity has been attributed by the Central Committee to a pronounced shortage of skilled manpower and to various manifestations of poor labor discipline and faulty management. Chief among the cited shortcomings in the field of labor are excessive absenteeism, resulting in part from inadequate medical and public dining facilities; loafing on the job; and a generally negligent attitude toward work that entails a loss of time and a low quality of the product. On the management side, the main shortcomings include poor organization of production, acceptance of unjustifiably low work output norms, and labor hoarding. Both workers and managers have been accused of a reluctance to adopt progressive production techniques and of frequently putting their own personal interest or that of their enterprise ahead of the public good. A disorganization of the material supply arising from frequent noncompletion of production assignments and poor coordination among plants and industry branches has also been cited as an important factor responsible for substantial losses of worktime and, consequently, of reduced productivity.
