This. Especially the last part ^.^Have everone that she is making claims about go to the manager and file harrassment claims. Simply stating that you are worried that with the kind of accusations she is leveling against so many people you cannot work around her. Soon they will either have to make her work alone (problem solved) or they will have to get rid of her (problem solved) or she will stop making complaints (problem not solved but then you follow her home and beat her with a sock that has soap in it...then problem solved)
