Support from Management
The AT&T leadership involves their employees in the decision-making process, but personally, I don't think their goals are realistic.
They communicate clear goals, but these are not targets that are realistic, or achievable, without resorting to undermining the evaluation system.
Colleagues work reasonably well together, and mostly are honest in their interactions.
AT&T pays a lot of attention to the disabled, with a lot of emphasis on having necessary to support such persons.
