I mean i'm sure there is a ton of stuff we hate doing at our jobs but we do it cuz that's what we are paid to do.
For people in entertainment its tough cuz you can't just say oh i'll open up shop and do it my way like say most people who work as employers. If your an accountant and hate your bosses, your more than welcome to start up your own office as long as your willing to take the risks.
For wrestlers its WWE or well nothing else if you want the fame (I know geeks will say Japan, ROH, and a bunch of other stuff most normal people don't care about)
That being said is there a degree of risk that a performer can take by saying no this doesn't make sense and this character fits me more...sure you can do that but it's been 50/50 success rate where some go on to be bigger stars by being defiant or you get deavored and lose your income.
I can't knock anybody who would take the safe way and keep their income stream and career, especially if they have families. If your someone like CM punk and saved your money and you want to play hardball then your more than welcome but you gotta know your place and whether your perceived to have the talent to be a hard ass defiant pain in the butt to get their way and knowing the history in WWE are black wrestlers willing to bet they would get as much leeway as coked up Michaels or CM Punk who bytched his way to the top
