I cant say to much about Arriva as I work in the head office for the North West and Wales, I did 18 years driving before that.
Its not the company it was the shifts and the attitude of the public and other road users that got me fed up, then after a major accident I thought it was time for a change, did some courses and got into the head office Monday to Friday 9 to 5 and Im very happy there.
I started when it was Ribble, that was split in 1986 at deregulation to form Northwestern Road Car Company which was bought by Coweis of Sunderland, this then changed the name to Arriva a good few years ago, I have to admit its a lot more organised and regulated than it was under Northwestern.
I suspect you will be joining Arriva Midlands, you have our old MD there and one or two of his directors transfeered there last year, one of my old sparing (verble ) partners went there and is now a director I think
I personally started to hate driving and the shifts mainly the violence and threats and not being able to do anything about it.
