Since there was limited work for free African Americans in both the North and the South, where did many freed slaves end up working?

they started to work mostly in cities or also known as the promise land other tried to build all black communities.

freedom of speech is also protected by the 1 amendment.

explanation:

here is pretty much what the 1st amendment says:

congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances.
