A greater understanding between the Ring Master and The Clowns? Somewhat risible, no?
I used to have to call Crewing at the end of each shift. The line was always busy, or so one used to find. No problem. Go off duty. Call crewing each hour on the hour until you get through. That's a duty call then. Twelve hour rest, or whatever, starts from the time you put that telephone receiver down having spoken with Crewing.
' Course, you can only do that if you're fairly well up on the Seniority List. But it doesn't half make 'em squeal at head office!
Great Fun!
