A big mature corporation is usually continuously downsizing and upsizing at the same time.
Continuous downsizing is an experienced corporation's alternative to firing. Low performers, folks who cause friction, folks who are paid too much, are identified as possible candidates for downsizing. Folks trickle out, week by week instead of firing, which requires excess paperwork. If there really need to be cost cuts, corporation can simply expand the size of the downsize, shed heads, and move forward gracefully.
Continuous upsizing is the way organizations get low cost talent into the org. Instead of paying an experienced strategist $150K whose skills might be ten years behind the times, they can pay an advisor $90k and get youthful vigor, willingness to take on two+ jobs simultaneously, and buy leading-edge skills. Corps can expand or contract continuous upsizing as needed too.
