We just have to point out that there is a big difference for temporary workers in all industries, in agriculture or others, between their rights under the law and their actual rights. Most of those rights depend on the worker. It is up to the worker to make a complaint or express a desire to unionize.
In Canada, because their status is completely dependent on the employer, it is very risky for them to do something that could be seen as being against the employer. For that reason, there is a lot of reluctance among temporary workers to unionize, to file complaints under employment standards or to ask the CSST to step in. We have to remember that their temporary status creates a difference between their rights under the law and their real rights.
