In addition to pumping real estate valuation, it seems like moves like this are a form of cutting workers without having to do layoffs. They know a large number of workers are wont be able to readjust, and will have to quit.
And the ones most likely to quit are ones that feel they have a good chance of easily getting another job due to performance/experience/education, leaving the company with the people unsure and desperate to keep the job.
This surely improves quality, productivity and motivation at the work place, yup yup.
