I'm hopeful that Qantas can improve it's service and reputation with customer and employees. Currently with the repatriation flights going ahead it's a good start in mending the reputation and will overshadow lots of what is happening currently in the courtrooms.
For those who can remember Vodafone went through a Vodafail phase in 2010 when their networks and nationwide drop outs in Australia. Vodafail article for reference. I worked as a retail assistant at Vodafone during this time and it was brutal having waves of customers coming in and abusing you. It took years to repairs this and it will be the same for Qantas.
What will need to happen and is probably happening in the background is quick wins, short-term and long-term goals to repair Qantas's reputation. This will however need to be balanced with competing strains such as maximized profits.
Have Vodafone recovered from this?
I was with 3 when Vodafone acquired them, so I got caught up in Vodafail, and I'm still reluctant to return to them (and I left them in 2013). Having said that, I was on Vodafone's wholesale network for a couple of months in 2021 (through iiNet). While I didn't have any issues, if I knew iiNet used Vodafone's wholesale network I wouldn't have touched them.
