I'd like to ask about the meaning of "labor movement" in the following context:
The varied reasons for labor movement have generated certain typologies of migration that are useful in distinguishing the different characteristics of migrants, their causes for migration, length of stay abroad, modes of entry determined by the laws of the host country and the motivations of the migrant. Temporary labor migration is the relocation of a worker to a place of work outside of his home country for a limited period of time as stated in the terms of a labor contract; whereas permanent labor migration is the resettlement of a worker in place outside his own country in perpetuity. It is worth noting that the term relocation is used to refer to temporary labor migration while the term resettlement is used to refer to permanent labor migration.
Do I understand correctly that "labor movement" does not imply "association of workers" (like trade unions) and means in this case relocation of workers, i.e. people (workforce) moving from one place to another?
I believe we should not view this expression "labour movement" as a set-phrase, and perceive each constituent part separately. Consider it as follows: "labour" (standing for working people) are in the process of moving somewhere else.
