The company identified the need to invest in automation to reduce manual handling, reliance on labor and reduce wage costs. The company is still citing challenges with labor. Either very little automation has been put in or the issues around labor are so chronic that its negated any gains from automation. The recent report only seemed to mention capacity increase - nothing on automation gains so picking little has been implemented.
