Kronos question

Does your store use all of the features on Kronos? Like shift swap or request to cover? Because my store doesn’t. In my training it showed us how to use Kronos and all the features but then I was told by the store manager that we don’t use Kronos like that and it’s only used for looking at your schedule. And she told me if I wanted to book a day off I was to write it down on a piece of paper for her. The features in Kronos are easy to use so I’m not sure why my store doesn’t use them. I’ve worked at a different company that uses Kronos and had no issues using it to cover my shift. Thoughts?
