Better or worse than the rest? How are coops managing on management?

I mentioned last week that The Guardian is currently running a series of six pieces from me on the theme Can coops compete?  The second in the series considers management issues and was published today (here).

Are coops condemned to see the best and brightest management staff heading off to, say, Sainsburys or Tesco?  Or – in principle at least – can coops, because of their ethical values, attract more committed employees?

And what about the way coops train their staff?  Should cooperative business education be different from conventional business education?
