So... a co worker and I worked out that we are taking turns on Wednesdays. So that's today. One week she'll work it, next week me, so on and so fourth. Today was supposed to start the switch so I texted her and reminded her. She says "yes I am but don't want to" should I just take her shift or no. I'm not doing too good with my ppd, and getting treatment during the day. But today is my first day and feel like I'll be exhausted by the time I get done. But could use the extra 4 hours even though we are usually dead and I don't make tip money. Ugh. Idk. What do yall suggest
