Not quite right.
Operations Resource Manager formerly known as the TCS (Train Crew Supervisor), they deal with train crewing issues, such as being late for work, sickness, cross covering, utilisation of spare crews, cover crews and so on.
Their job is to cover all of the work that the CRO (Centralised Rostering Office) may have missed or couldn't cover, so that the service runs. However as I and many others have found out, that when the brown stuff hits the high speed rotating ventilation device like it did yesterday and you can't get through to them on the phone or directly in their office, people wait & wait until such time as they give up & go, especially when they've done their hours & the obligatory 30' overtime and I for one won't do any for them especially if I've been up since 0245!
No one's going to thank you for screwing the job up if you're exhausted and add to the problems.
The problem they're going to have centralising everything to two locations which are Southampton & Waterloo is that you'll lose the all important local touch & local knowledge and knowhow.
If I say something to a Waterloo ORM about something on the Alton line or Ascot branch, they wouldn't have a clue what I'm on about, yet if I say the same thing to a Woking ORM, they'll know exactly what I'm talking about and be able to deal with it far quicker.
