Take a look at the conditions under which your staff work

You can perform good work in poor space and under poor conditions, but it is always easier to do so when the 'environment' is conducive to prolonged effort, provides what is necessary and makes the workers feel good about themselves.

 

So take a look at the conditions under which your staff work. Are they 'up to scratch'?  If not, is it because you really can't afford better, or simply that you haven't bothered to look before ... and have accidentally shackled your workers by not bothering to think of their real needs.
