From Foreign Policy:
As I noted in my piece, the president has made the colloquial phrase, "Monkey still working, let baboon wait small" her campaign slogan. It's an appeal to Liberian voters to keep in mind that recovering from 20 years of civil war takes time, and they shouldn't make any quick decisions or judge her performance before she's completed her work
This is a campaign trail quote from the current Liberian president Ellen Johnson Sirleaf. The first part ("Monkey still working") I understand to mean she's saying she still has a job to do. It's the second part I don't understand. Also, (this may be cultural) what do the monkey and baboon symbolize?
