I am QC here at a small food production company, this is my first QC position so I am still learning. I have been having some issues with employees not washing their hands after using the restroom. The reason I know is because sometimes either myself or a coworker are in the restroom as well and we hear people flush and simply walk out. Usually when I get out they are gone and I can't see who it is. Maybe a hand washing refresher might help, but I would like to hear what others would do.
When I witness this I go in to production area and supervise the hand washing area to ensure that people wash their hands before commencing work and they do. However, this is a very serious issue and I was hoping to get some insight on what steps I can take to fix this.
Any help is welcome, thank you in advance.
