Line Management is the management of employees that clearly indicates the responsibilities and reporting structure throughout an organisation. A Line Manager is the person who is directly responsible for managing the work of employees in a company or business, and who is one level above that person.
Reference Definition by Wikipedia: Line management refers to the management of employees who are directly involved in the production or delivery of products, goods and/or services. As the interface between an organisation and its front-line workforce, line management represents the lowest level of management within an organisational hierarchy (as distinct from top/executive/senior management and middle management).
