When I’m put in charge of employee policy, I’m definitely adding this poster to the handbook. And posting it next to the cafeteria.
Edited to add that my brilliant German speaking readers have translated the poster for me (I’m still learning “Das Auto ist Blau.”) and it is an anti women’s suffrage poster, not an anti nose picking poster. I still want to use the poster, I’ll just remove the political language. Although incidentally women’s suffrage is very recent on Switzerland.
Definitely no nose picking at work.
