Despite AT&T HR calling you "managers," a lot of you are not supervisors per the definition of the NLRA
(11) The term "supervisor" means any individual having authority, in the interest of the employer, to hire, transfer, suspend, lay off, recall, promote, discharge, assign, reward, or discipline other employees, or responsibly to direct them, or to adjust their grievances, or effectively to recommend such action, if in connection with the foregoing the exercise of such authority is not of a merely routine or clerical nature, but requires the use of independent judgment.
Many of you ARE eligible for coverage under the NLRA. Keep that in mind if you find that you are being inadequately trained for your CP assignment. Online courses with quizzes that you can copy/paste the answers of is not a stand-in for actual field experience and expertise.
Would you hire an electrician to work on your teeth if he took 60 hours worth of online courses and practiced once on a dummy? I wouldn't, but I'll hire them to do electrical work.
There's a reason why AT&T pays premium for people with actual know-how. You're not going to supplant a professional and you'll just put yourself in unnecessary danger. All for a company who doesn't care about you.
