Gate Hiring: when there is a large number of unemployed people, it is usual to find job-seekers thronging the factory gates. Whenever workers are required, the people who are available at the gate, are recruited in necessary number. This method can be used safely for unskilled workers. In some industries, a large number of workers work as badly or substitute workers. Whenever a permanent worker is absent, a substitute is employed in his place from among the people at the gate.
