Agriculture labor may be defined as labor who works in agriculture or allied activities for the whole or pat of the year in return for (in cash or kind or both) for full-time or part time work. The agriculture laborer has no risk in the cultivation, and no right of lease or contract on land but merely works on another person's land for wages.

Agriculture laborers can be classified into two broad categories:

1. Landless Agricultural Laborer: The laborers don’t posses land and can be further sub-divided into:

(i) Permanent Laborers attached to cultivating households: Permanent or attached laborers generally work on some sort of contract. The wages are determined by custom or tradition.

(ii) Temporary or Casual Laborers: Casual labourers are engaged only during peak period for work. The employment is temporary and labourers are paid at the market rate. These labourers are not attached to any landlords.

2. Small and Marginal Land-Owners:  These are very small cultivators whose main source of earnings due to their small and marginal holdings is wage employment. These laborers can again be divided into three subgroups:

(i)  Cultivators: Cultivators are small farmers, who possess very little land and therefore, have to devote most of their time working on the lands of others as labourers.

(ii) Share croppers: Share croppers are those who, while sharing the produce of the land for their work, also work as labourers.
