Two issues: how AT&T reduced the workforce without public layoff notices and the implication for other Former and current employees tell the same story about how AT&T avoided having to issue layoff notices as required by the 1988 WARN Act. From one source:
AT&T has done a number of #outsourcing actions since 2006-ish to different companies include #Accenture, #IBM and #Amdocs. Thousands of employee division in IT which was outsourced, and continue to date for the most part. The significance of this? My source indicated Amdocs issued WARN Act notices in California, where they have stricter requirements, but AT&T and contractors avoided having to announce reductions in Other cities where not required,, due to public perception of the company
No doubt AT&T plans to completely vacate many building across US, after their lease expires, in the meantime the numbers of employees at both buildings will continue to dwindle, there you go Layoffs will continue as the leases for buildings expire, obviously nothing to do with job performance.
