Yes. A team leader IS a manager.
“Team leader” is a name that is often given to denote the role of a first level manager. The purpose of the team leader/manager is leading and managing the workforce who operate “on the front line”. The role is a vital one because the front-line delivery of the product and service is where the “rubber meets the road”.
Therefore, the whole organisation’s success stands or falls on the ability of the workforce to get the job done, on time, on budget and to standard. It is the Team Leaders job to ensure this happens.
