It may also be resulting from a decrease in average productivity of work groups as a result of a number of reasons, the most important of which are:A- Quality of methods used in handling goods. Many ports in developing countries still depend on traditional methods of handling goods on multi-purpose berths, relying heavily on labor intensity and use of some old equipment and cranes, which leads to a reduction in production efficiency and the inability to lift Production rates to economic levels that are commensurate with the increase in movement and development in transportation methods. B- Nature and systems of operating labor force in port by shipping companies when it do all the operations of handling, storing and transporting goods in port, where the workers
