Rumor had it they are hiring 30 for one class and possibly a pool for the future. Although the classroom can theoretically hold 30 students, good luck with OJT for these guys. Offers did go out this week from what I heard.
On a somewhat related note, AA today also put out a posting for more Sector Managers. Rumor has it in addition to the 6 sector managers that went back to the floor from the bridge in the last class, even more likely put in for the job this time and may have gotten it. If that's true, that would be at least 8 and possibly more than 10 sector managers that have come off the bridge to the floor in the past two years. (FYI, I don't recommend putting in for the position as a backdoor way into dispatch.)
