I'm not sure what the issue is or what happened but....
Just like every employer everywhere, they are hiring inexperienced employees for cheap wages, etc.
My experience...The women behind the cutting board "know nothing about fabric, etc". Luckily the JoAnn's I visisted at home had a great Manager and the women were NICE. I got to know them well. When I was in the store, they would ask me to help with customers. I helped just about every time I was visisted.
I could tell you "many" like stories but I could write a short book.
Sorry for you frustration. Maybe we should all send JoAnn's a message and plead for experience workers.
