With that scheme, workers were tied to their employer. That was then removed because it was recognised that it is incredibly problematic. If workers were tied to an employer and wanted to leave, they would lose their visa and have to return to their country of origin. Even after that provision was removed, workers could only come for six months, which then meant that if they only had two months left on their visa, it was very hard for them to find new work and to change employers. In practice it was very difficult. Similarly to the previous SAWS scheme, technically you could change employers, but in practice it was very difficult, and in practice is what matters.
