Within the word work, a monster can be found attacking victims for reasons like age, color and sex.
Each letter in the vertically written word "WORK" is turned into a character symbolizing this concept.
W = Teeth = Monster/vampire
O = Egg = Age Discrimination
R = Red Man = Color Discrimination
K = Woman = Sex Discrimination
As for the colors:
Black & White = Darkness, Nightmare and Mystery
Red = Violence
The slogan is simply, "is your work a nightmare?", because those who are suffering from discrimination will simply consider their everyday work as a monster, and each letter in the word "WORK" is a nightmare for them, and a symbol of the thing they are discriminated against.
