There is no limit to the hours graft you're expected to do, and in our brigade there are no reliefs.
That said of course at a protracted incident any good commander will realise when his crews are too tired and need to be replaced.
In the bad old days Im sorry to say that some crews used to "draw out" the time they were at incidents to obviously get more money. Thankfully this practice no longer continues - flexi duty officers often attend shouts and keep an eye on what is going on, and of course the salary scheme irradicates this problem anyway.
The brigade are proactive and always try to ensure that it's retties are released from protracted incidents to attend to their full time job commitments . Not always possible of course, but they do try. So the goodwill works both ways.
As you know you do get some Retties who give the rest a bad name. Some constantly whitter on and moan about the job, some pose with badges all over their cars declaring theyr'e on call, or drive to station like Nigel Mansell when their pagers go off etc, fortunately for the most part the Retties I've worked with are responsible, committed to their jobs and professional.
Many Retties are now getting much better training commeasurate with their wholetime counterparts (allbeit over a longer period of time) long gone are the days where Retty's had did 4 days training
and we permitted to ride on a pump!
Anyway Prof I heard that when you began your long illustrious career in the Fire Service Green Goddesses hadn't even been invented, that horse drawn appliances were common place, and Colin Todd was only 55
