Kohl's POS Line Monitor for Black Friday?

I am new to the job and don't know anyone yet to ask. What does this consist of for Black Friday? I know obviously it's managing lines, but what do you have to do? Will I have to work POS throughout the day as well? Also, I am doing OMNI Fulfillment on Thanksgiving day, what is that and what does it consist of? Thanks for the input :)
