Reading these arguments is interesting. I don't know how many Disney employees who will be called back to work when the park opens are elderly, have underlying conditions, or are smokers. Probably quite a few? I assume most of them need to work, would be ineligible for any kind of assistance if they choose not to return and are looking at a bleak job market if they want to find a job that's less risky.
Anyone returning to work is assuming some risk, and based on the union agreement specifics that were released yesterday, Disney and the workers have agreed to some risk mitigation in the form of a mask requirement for them and for guests. Maybe it'll work and stay mandatory for along time, maybe the employees will decide the hassle and discomfort isn't worth it and ask that the requirement be dropped from the agreement. Until then, the least anyone can do if they choose to go to Disney on a vacation and take advantage of these people's risks is to do as they ask and wear a mask and follow social distancing, even if you don't think other people will, even if other people aren't, even if you think mask wearing is stupid and unhelpful. Disney has definitely accounted for those people and likely have a plan to deal with them, no matter how ineffective any of us may think it is.
That personally seems like the best way to move foreword to me.
