Analysis of information sources in references of the Wikipedia article "Plantation complexes in the Southern United States" in English language version.
On larger plantations, the planter's direct representative in day-to-day management of the crops, care of the land, livestock, farm implements, and slaves was the white overseer. It was his job to work the labor force to produce a profitable crop. He was an indispensable cog in the plantation machinery. [...] The overseer has usually been portrayed as an uncouth, uneducated character of low class whose main purpose was to harass the slaves and get in the way of the planter's progressive goals of production. More than that, the overseer had a position between master and slave in which it was hard to win. Directing slave labor was looked down upon by a large number of people, North and South. He was faced with planter demands that were at times unreasonable. He was forbidden to fraternize with the slaves. He had no chance of advancement unless he left the profession. He was bombarded with incessant complaints from masters, who did not appreciate the task he faced, and slaves, who sought to play off master and overseer against each other to avoid work and gain privileges. [...] The very nature of the job was difficult. The overseer had to care for the slaves and gain the largest crop possible. These were often contradictory goals.
