Amazon said it will examine its performance review systems and attrition rates as part of its diversity, equity and inclusion goals for 2021.

Amazon has said it will examine how it conducts employee performance reviews as part of its 2021 diversity, equity and inclusion goals.

In a memo sent to employees and posted on the company’s web site, Amazon’s HR boss, Beth Galetti, said the company would look for any “statistically significant demographic differences” in performance ratings conducted in the first quarter of this year to identify any problems and take action where necessary.

Galetti said Amazon hopes to retain employees at statistically similar rates across all demographics as part of its goals for this year.

Recode reported in February that Black Amazon employees are promoted less often and endure harsher evaluations than their non-Black colleagues, citing interviews and internal data.
