Worked for a while out of a London Branch/spoke. Hours and lots of week-ends, so can be pretty hard at times.
Their GPS systems are awful, and planning of routes insane and very cost ineffective.
Poor customer notification of late deliveries from offices/customer services, so poor old driver gets it in the neck if you are late, even if the delivery from Central warehouse is late into the depot or the route planning daft.
The place was a revolving door with new drivers in and out, many here for a very short time.
If you need something to tie you over it helps but pay is poor and not many opportunities for overtime despite what they say.
