It is tempting to do a walkout or make some other bold statement.
But you are only hurting your livelihood. This company will not suffer if you leave.
Your teammates or clients might, but Fiserv doesn't care.
Don't quit in a fit of rage. I had to hold myself back from doing this several times until I found something new. You have bills and obligations. Plus private insurance is a huge burden.
Be patient. Finding a new job takes time.
