Weve spoke about this before How many on a walk?Its 8
Got it from the Lighten the load -New CWU Safe Working On Delivery Guide
I had 10 today

went to my DOM told him my union said i must only take 8

He asked me where i got that from,told him the above

he then phoned DSM,abot 15 mins later he came round to my frame and took 2 of me

.Later on whilst out on delivery up pops my DOM in a van delivering my 2 extra stirs

He also took 3 of another guy,i had a look and it was just 2 of us out of 32 who had more then 8.
