Okay for now, but not for long - Part-Time Sales Support Fastenal Employee Review

It feels like those who are working very hard and doing their jobs and criticized more heavily by management than those who are just barely finishing their work. It's very frustrating to receive criticism for doing something in a way that the manager doesn't prefer, while another employee isn't doing the work at all and hasn't received any feedback. Positive feedback is EXTREMELY lacking. The internal inventory management system is complete junk. Training was poor. I learned what are apparently "key elements of the job" after I'd already been there for 4 months.
