A more thorough explanation:

A strike fund is a type of fund created by a union to provide financial assistance to its members who are on strike. The fund is designed to help members cover their basic needs, such as food and housing, while they are not receiving wages from their employer.

For example, if a union member goes on strike, they may not receive a paycheck from their employer. This can make it difficult for them to pay their bills and support their family. However, if the union has a strike fund, the member can apply for financial assistance to help cover their expenses during the strike.

Another example is if a union is planning to go on strike, they may start collecting money from their members to build up the strike fund. This can help ensure that there is enough money available to support members during the strike.

These examples illustrate how a strike fund can be an important resource for union members who are on strike. By providing financial assistance, the fund can help members stay afloat during a difficult time and ensure that they are able to continue fighting for their rights and interests.
