While parties are one type of political organization that may engage in some or all of those activities, they are distinct in that they typically focus on supporting candidates for public office, winning elections and controlling government.
The most well-known type of political organization is the political party. Political parties are directly involved in the political processes of countries with party systems, of which there are several types.
In multi-party systems such as India, Pakistan, etc., there is no restriction on the number of parties allowed to be in operation at any given time. Under these types of systems, people are free to participate in the political process both through elections and by forming their own political parties as they please.
In single-party systems, one political party exercises control over the government. Unlike under other systems, single-party systems do not necessarily extend democratic privileges to the citizens. This means that citizens have little say regarding political subjects.
Two-party systems are similar to multi-party systems in that power is not concentrated in one party and that parties have to consider the opinion of the general public in order to retain power by winning elections.
Most two-party systems are technically multiparty systems but all power is effectively concentrated amongst two parties or coalitions.
Another type of political organization is the party coalition. A party coalition is a group of political parties operating together in parliament. Oftentimes, party coalitions are formed after elections have taken place and no party has clearly won a majority seat in parliament (e.g. the AAP-Congress Government in Delhi). Other coalitions are formed prior to elections and are effectively agreements between two or more parties to run jointly in elections and to pursue similar agendas (e.g. the National Democratic Alliance in India, and the Liberal/National Coalition in Australia). The electoral thresholds for multi-party alliances are set differently in many countries depending on the number of parties.
A technical group or mixed group is a heterogenous parliamentary group composed of elected officials from political parties of differing ideologies (or independent of any party) who are not numerous enough to form groups on their own.

Unlike other political organizations, labor unions do not directly participate in elections, although they may campaign for parties and politicians supporting their positions. Labour unionization is a way for workers to maintain unity and preserve their rights. Often, major corporations antagonize the principle of labor unionization since it results in heavier employment regulations which restrict the powers of big business to fire workers at will, effectively causing economic difficulties for such companies.
