Which methods of resistance were used by slaves?

"Day-to-day resistance" was the most common form of opposition to slavery. Breaking tools, feigning illness, staging slowdowns, and committing acts of arson and sabotage--all were forms of resistance and expression of slaves' alienation from their masters. Running away was another form of resistance

Hope this helps :D
