Yes. Ask mgnt when you can expect it, they hate that! Every person that worked it will get that back pay, hopefully you can see how many days you worked it. Ask regular the back date she is getting paid from. Ask to see all time sheets back to the retroactive date ,( unless you have all of your pay stubs). (You could probably go on lite blue), ( I like to do it in front of them and act like I know what I'm doing) look thru each one for your name and start counting you will have a idea of how many days. Before you do this ask mgnt how and who figures this out. I love to see them squirm. Knowledge is power. Ask reaular to keep you informed when she gets her money so if you dont you can file a grievance
