employee tools

For those that work in a shop & are incharge of employees handheld tools, how do yall go about collecting everyone’s tools on the shop floor? I handle about 100 employees in my shift and going around collecting tools feels like I’m wasting time when we can have a better system in place (our second shift for example leaves their tools in our QA department for me). I’m a one person team for the whole company so there’s stuff I’d rather be doing over convincing employees that I need their tools. Auditors have suggested leaving boxes in each department to have tools dropped off whenever I handout calibration papers but i want to see what other systems people have in place for this.
