This Week’s View From The WNDow Seat

Michelle>> Last week’s surprise announcement sparked some great conversation from you about what the acquisition of AirTran means for every Southwest Employee. We’ll take a look at what’s happened since the announcement. Hi! I’m Michelle Brookes, Manager of Health and Welfare Benefits.

Wayne>> And I’m Wayne Davis, Health and Welfare Benefits Coordinator. Welcome to the WNdow Seat!

Michelle>> Gary talked about the acquisition plans and answered a number of questions from you in his Town Hall meeting.

Wayne>> Top of mind for many of you – how will we retain our Culture? Who better to speak on that topic than our Senior VP of Culture and Communications, Ginger Hardage.

Ginger Hardage – Well our culture is what sets us apart – it’s in our DNA. Already, there are great examples of the welcoming Southwest culture emerging. In fact, a group of our flight attendants completely on their own started a Facebook group to welcome the AirTran crew members. And you know, crew members are what AirTran employees are called. Then there’s a story of an AirTran pilot who was on final approach into BWI when the controller at the Potomac approach told her to follow her soon-to-be company. Before she could answer on the radio, the Southwest pilot she was told to follow responded “Welcome to the family.” It’s just stories like these that show the true colors of our employees. It’s up to each of us to keep our culture going strong, to really OWN it, and to welcome the AirTran employees to our Southwest family.

Question>> A number of Employees have also asked if the AirTran crew members will have to interview for jobs at Southwest.

Ginger Hardage – That question has been asked by many of Employees, so we included it in the Q&A portion of SWAlife, and on our website that is completely dedicated to the AirTran acquisition, that’s lowfaresfarther.com. But I’m glad to recap the response. As long as AirTran employees would be joining Southwest at their same role – for example, a Customer service agent to a Customer service agent, then no interview is necessary. But if an AirTran employee wishes to apply for a different job at Southwest – say a Customer service agent to a flight attendant, or a flight attendant to a Customer support & services rep, then they will have to interview. That’s just how it would be as a Southwest Employee wishes to change positions. And as always, we will follow our contract provisions that apply.

Michelle>> In the coming months, Gary will visit as many locations as he can to continue the discussion with you on this exciting subject!

Wayne>> Keep checking SWALife and lowfaresfarther.com for updates.
