Some drama in parade land...
TL:DR - some specialty costumes weren't finished in time for the reopening of Paint The Night, so the performers' gridded shifts were canceled until further notice with no option to switch to any other position. Someone made an anon Instagram account to call out the management who made the decision and less than 24 hours later, the account is gone.
For those who may not be familiar... having a "gridded day" as a Disney performer means for the length of this show run, you are basically guaranteed to work those days (typically 3-4 specific days per week). It's a big deal for the performers because it's consistent guaranteed work that they can plan the rest of their life around. And they turn down other work to stay available for their gridded days. And Disney is notorious for wanting to keep "consistency" in their experience, which in the past has translated to "if it's not ready by opening day, we're cutting it forever" (see Frozen 2016).
Out in the real world, It would be like showing up to an office job and your boss says "we weren't able to get a new computer for you to use yet, so we're gonna send you home without pay until it shows up. Unless we decide in a week that we've gotten used to not having you so we're not going to bother anymore."
