"I’ve learned the hard way with T...NO boss is your friend, Period!"
AT&T has over 250,000 employees if you include on-site contractors. In my day, it was closer to 300,000. That's the size of a city. You can't say in one neighborhood, that the situation there is the same as another neighborhood.
At my career at AT&T, I worked in 5 neighborhoods. Two had management I socialized with. They were fine. Three didn't. I wouldn't be letting the supervisors know what I was thinking in those areas, And some of those were the same operation, in the same business unit and only different cities. The biggest "neighborhood" I worked in had 1000 people.
One can't paint AT&T with one broad brush. I think certain areas can be painted with one brush, such as call centers. But, I've worked in various business units and different locations, and if it wasn't for the common payroll, common 401K, etc, I might as well be working for different companies.
I made it to the finish line, so something worked. My advice stays the same - to the OP, if there is no indication that they're trying to reduce force, I wouldn't disclose anything to management unless they are people you know off the job. I don't see the advantage. If an offer appears, it will be filled by seniority anyhow. IF something shows up, put in for it, and if your boss asks, say something apologetic, like, "I love working for AT&T but I'm not going to live forever".
