The paper has focused on important leadership and management strategic roles in employee retention with reference to a London higher education institute. It analyses some of the reasons for high turnover and theories around effective leadership and management roles in retaining hard working employees, with reference to teachers in a higher education institution in inner London cities. When discussing teachers, it includes lecturers that teach in higher education. Retaining hard working teachers has been an issue in HE institutions, particularly, since the Brexit and COVID-19 crisis, therefore, important to explore the issue in the context of the leadership and management strategic roles to reduce high turnover. The mini research uses mixed methods, quantitative and qualitative data collection with thematic analysis of the key findings from literature and comments from teachers on why they will like to stay or leave their jobs for another employer. Having sampled the opinions of small sampled participants and the literature sourced, it is obvious that teacher retention is a big issue in education with some teachers wanting to leave or stay. Those wanting to stay will do so if they are motivated with better pay and compensation and effective leadership and management of education institute and those leaving would live due to poor pay and heavy workload. The most interesting to note is that most of the participants love the job they do as long as their students are achieving their qualifications. [For the complete Volume 21 proceedings, see ED629259.]
