Employee engagement should start where you need it the most.
This isn’t necessarily a bottom-up deal that begins with your most junior employees. It could be your leadership team to start, or at an organisational, divisional, group or team level.
You have to start in the right place and approach it in the right way to meet your specific needs then build on that, growing it in the specific way that is right for your organisation.
When and where you start must be unique to you.
