Salary increases when employed at United Healthcare are minuscule at best. The only time you will be able to self direct your earning potential is upon hiring and when you accepted at your next job. Carrot is dangled, then they change the targets and make them impossible to reach. It has always been like that and always will. Employees are pitted against one another and all are cogs in a wheel even management. There is no opportunity to help a team member because you will be penalized. Use UHC to stack your resume and learn the business and then move on. You may find happiness. Hard workers are not compensated. Good Luck.
I agree completely with @Li0ZV4x-2Jtvr, especially the part about the raises. If you are counting on that to bump up your savings, don't hold your breath.
