Companies in general only value performance... and even then, they prefer to have performance at the lowest cost - union or not.
As an individual - you can work hard and move up the ranks, and on to a possible better career. The limit is 'you'.
As a union member, you're tied in by seniority as a general rule of thumb. The limit is 'the union'.
Unions in ATT only extend, at least in the Mobility side, to the RSC's once you hit management they disappear and then ATT really sticks it to you. The culture between the two is not friendly and rarely smooth. Not to mention your ability to move up inside of that massive company is extremely rare within the first 5-7 years and many times never happens as the good old boy system plays it self out due to the older managers who have sat at their job for the last 10+ years.
