They are cruising on the coat tales of an out of date reputation, not the reality of being in the business.
Lack on inspiring leadership
Poor behaviours are ignored in exchange for delivering results.
Poor culture within the HR Team, often met with hostility from many when trying to do your job.
Major lack of progression - opportunities due to very low movement in more senior roles. Often job changes only come about through re-orgs (which are happening more and more frequently).
Diageo is big on promoting their parental leave, flexible working, etc - yet internally people regularly have to fight for flexible working patterns ie. going part time or not being present in front of their line manager.
