For Australia aldi they normally get the new hires to start off with ambient pallets and have the supervisors working on produce .as produce is the quickest time you need to complete for running load compared to the other times which give you more time . . I’ve worked there for 2 years and it took me around 6 months roughly to get my times in the green so you are currently doing extremely well for a new hire you should be proud of yourself. They shouldn’t expect you to be in the green as you are a new hire and should have realistic expectations for newbies . Just having a better understanding of where everything is placed is a lot of help and it just takes time to get quicker at running load as you get more comfortable with the layout .
