What is the definition of Unions Macabre?

Unions macabre is a delightfully grim term that combines the word 'unions,' which we usually associate with workers banding together, with 'acabre,' the morbid term for something related to death or decay. So, it's like saying unions that are so morbid they're more interested in discussing the afterlife than the job market. Imagine this: "The unions macabre gathered in the dead of night, plotting how to turn the whole labor union into a zombie apocalypse, with strikes as the ultimate form of undead rebellion!"
