Hmm I'd have to disagree with that one a little. I use LM ('city' not express mind) every day and yes there are some guards who I have never seen do a ticket check yet in the years I've been using the service. However 2/3 usually do one and adding to that quite a few of them will chat with the regulars and do interact with the passengers.
The newer intake seem to be more focused on the ticket checking side of things though, which has caused issues believe it or not, however I fail to see how the guard can be blamed for members of the public not having tickets, it is up to the passenger to ensure they purchase a ticket. Personally I'd put RPI at the larger stations and fine the lot. Stations like Coventry have needed ticket barriers for years.
It is hard work on these services and we are all different. There is a lot of hassle to be had out there on these trains and our shifts are long and intense, not like the Virgin TM's who barely get onto a platform. Many of the time served folks are simply either sick of the grief they get from the high percentage of professional dodgers we carry, or just knackered. Working these trains from the saloon is harder physical work, coupled with the fact that on most of our trains the local door in the saloon is slower to open and close than the cab door. This means that with the amount of stops we make, it's not long before you're creating a delay which on our lines has endless knock on consequences.
Personally I work most of my trains and take as much as I can, not least because we are on commission and I feel it is worth the effort. But then I only do my basic shifts, I don't do overtime. Many would rather come in for a rest day and get the extra cash that way, I prefer to earn it while I'm already here and keep my own time to myself.
I do get fed up with the attitude you get sometimes, 'lazy cab dwellers' etc etc. We can go up and down as many as 5 or 6 times a day and may choose to stay in the cab for one trip, yet that is the one the complainers cite when telling us all how lazy we are. Then when you do a full check you get the grunts and eye rolls from the very people who will complain the next day that their ticket is never checked.
I have learned that the job here is generally an unwinnable situation, you are always causing dissatisfaction to someone or other whatever you do. I just get my head down and do as much as I can. How everyone else does it is down to them.
