The goal is not to save money. But there is a great deal of volume. In previous years, a minimum percentage of positions were posted. That percentage is increasing every year. Last year, one million positions were posted. It is almost impossible to have enough people to do all that translation.
So the reasons are translation volume and employer demand. They want positions to be posted not within a week or a couple of days, but within four hours. So demand is currently extremely high, and we have very little time to post positions.
