CHAPTER ONE
1.1 Introduction
Employment for individuals, means having a job or other gainful occupation. For a nation, total employment is a measure of how well the economy provides opportunity to all who are willing and able to work. In a statistical sense, workers are considered employed if they have either full or part-time paying jobs or are self-employed, even if they are not working at a given time for reasons of health, strike or vacation (Darby, 2003).
The growing and expanding economic responsibilities of governments at the Federal and State levels, have affected the capability of governments to continuously recruit adequately qualified teachers to meet with the expanding students’ enrolment in Nigerian secondary schools. Therefore, the use of Sandwich Programmes and part-time programmes of tertiary institutions in Nigeria, remains a dependable source of improving serving teachers’ professional and academic quality as well as improving the number of teachers for Nigerian secondary schools quantitatively and improving qualitatively with respect to standards (Mezieobi, 2006).
