Upward communication is communication that flows from employees to managers. It keeps managers aware of how employees feel about their jobs, their coworkers, and the organization in general.
Managers also rely on upward communication for ideas on how things can be improved. Some examples of upward communication include performance reports prepared by employees, employee messages in suggestion boxes, employee attitude surveys, grievance procedures, manager-employee discussions, and informal group sessions in which employees have opportunity to discuss problems with their manager or representatives of top-level management.
