In the current Rail magazine's report on the Night Tube dispute, it makes reference to TSSA claiming that accepting TfL's proposals would mean staff accepting changes to the 'LU promotion process'. Rather than another thread on the dispute itself, it's that reference to a 'promotion process' and what that currently means that intrigues me. The advice we usually get from HR at work is that the only legally acceptable approach to promotion in terms of equality requirements is for appointment on merit against whether a candidate best meets the competencies/experience set out in a person specification. However, the reference to a 'LU promotion process' implies that there is a specific process in LU. Can anyone please clarify what that is?
