Almost all busy ports tend to have seafarers unions, where the people who work in the said ports are members. The idea to form a seafarers union is normally fronted by an individual, before spreading and being adopted by others to form a critical mass capable of fighting for unionization. We are interested in identifying the factors that motivate people to establish such seafarers unions.
The first factor that motivates people to establish seafarers unions is the genuine, altruistic desire to fight for the rights of the seaport workers.
The second factor that motivates people to establish seafarers unions is the desire to benefit from the union dues paid once the trade unions are formed. The deductions made from the individual seaport workers (who form the membership of the unions) may look small, but cumulatively, they turn out to be huge sums of money. The folks who control such resources end up benefiting, even where that is not done through corrupt means.
The third factor that motivates people to establish seafarers unions is the desire to gain influence: as the people who become the leaders of these trade unions end up having a lot of political influence, which they can leverage on to get personal benefits.
