There are no blanket or automatic raises in DXC. Its exactly the same as CSC was.
You've got to score and 1 on your appraisal (the numbers of 1's being tightly controlled - you can perform to a 1 but will get knocked back to keep the numbers down), then it has to go up the management chain all the way to Mikey who will personally sign it off.
Guess how many people will get it...
As for the rest, the lack of pay increases is both about controlling costs plus encouraging you to leave of your own accord (without DXC paying your severance). After you leave they either don't replace you or replace you with a cheaper hire.
Years ago the CSC board (pretty much the DXC board) decided that money doesn't motivate employees. It motivates them of course, with multi million dollar bonuses to be played for.
Is this different elsewhere? Probably not in any established company that needs to "transform" the workforce with digital. Its a race to the bottom.
