Full employment is typically defined as a situation where all individuals who are willing and able to work at the prevailing wage rate are employed. This means that there is no involuntary unemployment in the economy, which would include frictional, cyclical, seasonal, and structural unemployment. Therefore, a zero percent aggregate unemployment rate would indicate full employment.
