Yang has never been "bossed" by Ruby, she adores her little sister and respect her as a leader, in fact she has been shown to be proud of Ruby when she lead the group when they were pursued by the Nevermore and the Deathstalker and when Ruby was made leader of Team RWBY.

Plus Yang has no reason to join her mother especially after seen Raven for the big selfish, cowardly and hypocrital woman willing to sacrifice her own family to save her own skin that she is and that she will not have a good relationship with her unless Raven really changes her way.
