So if what you are saying is true, why, if these American workers were so bad, has Disney more or less demanded that they stay on and “train” their replacements? When I was an Engineering Manager, I got rid of under-performers and I didn't keep them on the payroll to train their replacements. That's simply inviting a disaster.
I don’t work there but I can speculate:
Disney is making much needed wholesale changes to the IT dept.
They’ve got a Billion with a B dollar My Magic Plus Architecture that is over budget, behind schedule, and non functional in key areas and glitchy in other areas.
They are bringing in fresh eyes to fix the multiple problems. With a Billion Dollar Infrastructure, the new designers will need extensive appraisals of where and how things got to currently be.
We aren’t talking about a simply piece of techware.
And. What I’m saying is true that Disney’s IT has been horrible.
Ask any travel agent you know what they think about Disney’s IT platform.
