Let see, publically known are multiple ESPN employees who have gone on the record. My reporting history goes back to the Eisner era, where many CM's talked to me off the record in how the company culture was change from caring about the CM's, to treating them more like hired help.
Ask any of the old school Disneyland retirees that do appearances the question, and they will tell you about the shift over the last few decades, all going to less caring about CM's. I also think the CM Unions are now making the Employer/Employee relationship more toxic, as the Unions need to have a "bad guy" to promote Union Solidarity.
I have talked to many Knott's employees that left Disney and stated they were treated much better by Cedar Fair, and happy they made the switch. Some still work for both, especially those in the performance roles. To a tee, for example the Christmas Choir Singers work at both, and they love the freedom to perform at Knott's and match the songs to the group listening as compare to Disney's requirements of doing the exact scripted show, for the exact minutes allowed, no matter what.
Talk to Krazy Kirk and the Hillbillies where they prefer to work, and everyone of them don't miss Disney in the slightest, and their fans also enjoy their shows more now at Knott's.
Basically Knott's management actually listen to their employees and use some of their ideas to improve the park. Disney CM comment's fall on deaf ears, basically do exactly what I tell you and don't talk back. It starts at the top level of Management, and everyone has to follow the lead.
