In this case, I think NSP refers to the groups of reps that discuss different issues with BA. In the NSP both BASSA and Amicus(Cc89) had reps. BASSA had a larger number. I believe there are different NSP's to discus different subjects but all that is about to change.
My manager has told me that prior to the strike sixteen different meetings a month took place with BASSA. This is going to be reduced to one a month and that sounds good to me.
