New to Partnership Payment - New rules

After introducing this new scheme , there have been problems with new partners getting their payments. Hurdles that were put in the way had been that the probationary period of fixed-profit that a lot of practices put in place when a new partner joins. This period has new partners paid a fixed salary rather than a share of the profits for a short amount of time. When these partners have gone to apply to the scheme, they've been told that they are no eligible for the payment, as they are not profit sharing and also because when do become profit sharing after their probation then they will still not be eligible as they wont be 'new partners'.
