Brighton has roughly a 1/3 of all Conductors so just shows how flimsy the GTR sickness argument is in blaming them,it has been seen through by a lot of the public too. When I was rostering train crew it was pretty easy to predict sickness and the day to day circumstances but then again I was allowed to book overtime and rest day working. If I hadn't had these resources even with 4 sick would have made the job very difficult !!!
