Implementation of Labour Act in Ghanaian Public Industries – An Empirical Study of the Ghana Water Company Limited (Published)
The purpose this study is to investigate the implementation of the Labour Act, 2003 (Act 651) from the context of Ghana Water Company Limited (GWCL). A total of 10 management staff and 206 senior and junior staff of Ghana Water Company Limited (GWCL), constituting 216 were sampled for the study. Out of the 206 questionnaires administered, 149 responded in addition to 5 management staff who were interviewed, giving the total of 154 respondents for the study. Statistically, less than half of the respondents, 74 (48%), admitted that there were a number of challenges in the implementation of the Labour Act while 80 (52%) expressed otherwise. The study established that the implementation of the Labour Act, 2003 (Act 651) at the Ghana Water Company Limited is not up to expectation. It is recommended that a study in the private sector will contribute to a more in-depth understanding of the research topic.
This paper suggests an improved ratio estimator in stratified random sampling. Analytically, the bias and mean square error (MSE) expressions for the proposed estimator are obtained. Efficiency comparisons are made to evaluate the relative performance of the proposed estimator. In addition, an empirical study is provided to support the analytical study. Analytical and numerical results showed that the proposed estimator is more efficient than the estimator under study.
