'It is suitable for filling casual vacancies when work load is high or when certain number of permanent workers are absent.'

Which of the following is being referred to here?

Direct recruitment

The correct answer is option 1- Direct Recruitment.

Under the direct recruitment, a notice is placed on the notice-board of the enterprise specifying the details of the jobs available. Jobseekers assemble outside the premises of the organisation on the specified date and selection is done on the spot. The practice of direct recruitment is followed usually for casual vacancies of unskilled or semi-skilled jobs. Such workers are known as casual or ‘badli’ workers and they are paid remuneration on daily wage basis. This method of recruitment is very inexpensive as it does not involve any cost of advertising the vacancies. It is suitable for filling casual vacancies when there is a rush of work or when some permanent workers are absent.
