German management culture doesn't emphasize effective people management -- and the results show in low engagement nationwide.

Most German employees say performance appraisals don't meet the goal of actually improving their performance.

Workers who are not engaged or actively disengaged cost the German economy up to 287.1 billion euros annually in lost productivity.

Only 13% of the German workforce is committed to the job, according to Gallup research. As much as 20% is actively disengaged. But don't blame the affected employees for this -- the fault lies with poor corporate cultures that depress engagement and discourage productivity.

The vast majority of the German workforce is not engaged with its work. Though not a hot topic at last week's G-20 summit, this presents a serious threat to productivity -- and ultimately to Germany's gross domestic product.
