There are a number of reasons to return uniforms items. The item may get lost or stolen or simply issued twice by accident.
Go to the personnel page and open the PersonnelUniformItem tab to see the uniforms items that have been issued from Work Force Manager. Now that you are on this screen, you can see all the issued items with a button next to it "Return".
When you click on the "Return" button the below screen appears. All you need to do is provide a reason for the return.
Upon the completion of the return, there will not be any buttons next to the uniform item. See the white box on the screen? That displays the reason for the return and some snippets of information related to the item.
