A broad-banded pay structure that provided greater opportunity for employees to move
laterally and acquire additional skills through extensive
crosstraining was thought to be consistent with the development of a new culture in which employees would take the responsibility to develop broader skills through continuous improvement programs. The new culture also would include greater emphasis on performance improvement through paying the person rather than the job.
Please explain to me the emboldened parts.
I know "lateral" means "sideways movement" but i wonder what it means here.
