Shake up at work (again)

One again, I find myself showing up to work only to see memos posted all over that they are revamping the schedule template and that new schedules will be given out based on seniority. Once again I face losing my weekend schedule. I just got it back damn it!!! The schedule lady says she will get back to me by the end of the day...seems there are only a few left who do not know there new schedules and we are all weekend double people.....not good to be the last to be offered a schedule....probably will be offered the left overs......
