Brit Pete,
I haven’t worked for them, they are about 5 mins away though, so I se them often.
A chap I know who works near me used to work for them but he went off driving. He now does permanent nights (4 on; 4 off) as a security dog handler.
I think they were OK to work for but he wanted to be home more. He still doesa the odd bit for them now on his ‘4 off’ so they can’t be that bad!!
