Unless your plant has reached all of its profits-based goals, every employee on the payroll can improve some aspect of their job function, be more efficient, or expand their capabilities.

Some companies use a strategy where every employee has to be either trained or training to advance. This is aggressive… but such companies are best poised to handle expansion… or downsizing. 

There are always opportunities for your employees to learn… and for them to learn from each other.

I have been to companies with advancement policies which require each employee to be actively training someone else to to their job function. Failure to do so can result in them being disciplined or even fired.
