Research approach adopted in this study is positivism which supports the use of questionnaire for data collection as well as nomothetic research philosophy in management sciences. Accessible population for this study consists of ten manufacturing firms operating in Port Harcourt. Sample frame of seventy five which includes middle line managers, supervisors and union leaders were sampled using simple random sampling technique. Sixty three copies of the questionnaire were administered to middle line managers, supervisors and union leaders of selected manufacturing firms operating in Nigeria. Mean and standard deviation were used to analyse the research questions. From the results above, it was found that employees are not involved in the strategy planning and formulation process in many corporate organisations in Nigeria. Managers should ensure that teams at all levels should be involved in the strategy formulation and implementation process in order to build a shared vision and increase each individual motivation and participation to see the strategy succeed.
