GMB is the Union I and a few other drivers are in at our place. I have had to use them for advice over a dispute I was in with the comapny and they were superb. Emailed the area rep and had a reply within 3 hours on how to proceed with the dispute. Thanks to their advice I still have a job there. I have also used their free legal department which again was really good and saved me having to pay solicitors bill on an event.
All for just £13 a month which I get the company to pay for as I slow down and skank an extra hours work a month to pay for the subs
