I can definitely relate to this! Here are some things I've done that really seemed to work at my last job:
-training in small groups. I tried to use as many visuals as possible even though I had translators for the different languages. I would swab things like cell phones or "clean areas" that were actually dirty (cardboard on the floor that they pretended was a clean table for buckets, then would touch the bottom of buckets as they emptied the contents and said they didn't need to change their gloves). I also purchased a flurescing lotion (glowgel) and a UV flashlight, had them put the lotion on their hands then put on gloves. The UV light will show where hey touched the gloves to illustrate why having clean hands is necessary when putting on gloves. I then asked them to go wash their hands and shined the UV light on their clean hands. Many were still fluorescing and I used this as a way to show why washing hands thoroughly was important. People would usually grumble as I made them use the lotion, but once the UV light was out they were eagerly comparing their hands lol.
-I also read this book: https://www.amazon.c...y/dp/1493924885 Some of the examples are a little out there, but for the most part it got me thinking about different ways to do the training to really sink in. Like giving real world examples of recalls or illnesses of products similar to yours, or an actual recall from your own company's history, etc.
-I was lucky to have management buy-in (mostly) so I walked around with the manager and wrote up people if it was their second offence after training. This was by no means fun, but I wanted them to know that I was serious and that their manager is on the same page as me. Catching people with jewelry was the main issue.
-I also asked the production manager to let me work somewhere on the line for an hour per day/week as my time allowed. It allowed me to get to know people on the floor, and to really see the challenges people deal with and learn the process better than just looking at it. I noticed for example that I can ask employees to change their gloves frequently all day long, but if gloves are very far from them and they can't easily leave a running line, then they won't. We ended up having maintenance build 10 new glove dispenser holders that were mobile so we could arrange them around the lines as needed. People had very easy access to them and were now changing their gloves much more frequently.
Hope these are helpful, good luck!
