Vantaggi
I'm struggling to think of any - historically BT was once a vibrant, exciting and challenging business with many very smart people working hard to build great solutions for customers. Actually I last worked for the business in 1997, but the Glassdoor web form didn't allow me to go that far back.
Svantaggi
BT is in a massive hole, obsessed with TV rather than enabling fantastic communications for the UK and its global clients. The parlous state of UK mobile comms and broadband lies squarely on BT's plate and no-one else's. The management will blame the regulator, the government - who have mostly just failed to hold BT to acccount. The Italian fiasco is the icing on the cake, and I'm delighted to see that the regulator is finally forcing Openreach to legally separate - but still falls short of properly splitting from the group.
