tachograph:
Helen Stevens:
I am sorry if it offends you that I can read a tacho. It doesn’t offend me that you can reverse a truck. Afterall, it is your job, right?
It doesn’t offend me that you can read a tachograph chart and please don’t underestimate the abilities of drivers

I can read a chart and a printout and the tachograph display itself and I know that many probably most of the other drivers on this site can do the same 
Nor does it surprise me that some companies indulge in such costly and irrelevant activities as checking on speeds of vehicles even though it does not tell you why the driver was travelling at that speed, I’ve worked at one or two of them 
Tachograph, I never said I analyse every minute of the speed, but if I have a tacho that doesn’t look right, then the speed can be a very useful tool to tell you how the day panned out and where the lad was. If he’s galloping along at 56 then crawling for half hour stop start, then galloping along again, it’s pretty easy to work out that he was held up on the motorway. So I can pay that lad his overtime happy in the knowledge that he earnt it, and wasn’t ■■■■■■■ about somewhere. I think it helps to create trust, myself. When otherwise you might wonder why a trip down the road took the lad three hours when it’s only a half hour drive. Then you might potentially have doubt about what the lad was playing at, whether he took the scenic route to put extra time on the tacho. At least this way you know and are happy you can trust your lads. And then on a day when you really can’t work out what went wrong, you can happily give him the benefit of the doubt, knowing that he’s not out to rack up undeserved overtime.
All we ask of our lads is that they do they job we pay them for, in a legal way, to the best of their ability, and are honest and trustworthy. Surely that’s not too much to ask is it? Our drivers are very happy with us, evidenced by the fact that all will stop and chat, most have been with us for years, and nobody ever seems to leave! We don’t have a high turnover of drivers at all. We look after them, and they look after our customers. And everybody is happy. If you think we’re one of these big brother workplaces, you’re wrong. But nevertheless, I can read a tacho. 
It isn’t costly or irrelevant. It is very quick when you know what you’re doing, a 30 second comparison with the diary will tell me how a lad’s day went. And sometimes you can ask a customer to work a schedule around the other way for example, if you know there’s always a hold up in a certain place at a certain time due to shift changes, coffee breaks, peak driving time or what have you.
