To my former fellow ex FDS, CSC / DXCites, do not think you are stuck there. There is always an opportunity to move on. Consider dusting off / rebuilding your CV and getting out there on LinkedIn and other job search platforms. I did this and was lucky enough to get out, you can do the same. Just for the love of god don't say "I'm leaving because DXC is bad" in your interview, I've heard so many make this mistake.
If you need, take advantage of the current dearth in staffing to internally swap roles and get the training/experience you need, then move on. ITO and Workplace are desperate for more staff, and if you need to self study you can pick up a cheap SFF Optiplex PC and install your favourite Linux / Windows Server OS for that Unix / Wintel experience.
If you work on the BAE account, look at working for the client. They practically snap up competent DXC staff because they know how the operation works and know they can't be fooled by DXC fibbing. I know people who have gone on to become successful Service Managers, Architects, Project Managers and App SMEs working for the client direct. Same for Leonardo and Urenco, they have ex DXC Project Managers and Architects working closely with them.
Above all else, stop dumping on each other. MSPs may ultimately just be a sweatshop to maximise gains for minimal input but DXC is an especially terrible shop in this regard in that, unlike other places, the apathy and lack of involvement from mid-upper leadership is apparent. You have alternatives; Littlefish, Capgemini, Capita, ATOS all have a ton of ex DXC staff and work in the same spaces. Or as I said before, look at working for a smaller shop or with the client direct. We all deserve better, and know who the deadwood is. Don't be angry at people who got good terms & salary in their contracts be angry at the company. Don't be a crab in a bucket pulling each other down.
