Managers Perspective
It's a bit hard to use a radio or a mobile if your alone, injured ,and unconscious on the tarmac.Hence the need to work in pairs, we wouldn't want an LTI would we, coz safety is our priority.
It is my experience of late that all staff are out of the office and spread thinly around the ramp, even the senior is out of the office just to make things work.
Stick to shuffling papers!
