I never understood the attitude of some companies to fire an employee immediately if they make a mistake such as accidentally deleting some files. If you keep this employee, then you can e pretty sure he'll never made that mistake again. If you fire him and hire someone else, that person might not have had the learning experience of completely screwing up a system.

I think that employees actually makes less mistakes and are more productive if they don't have be worried about being fired for making a mistake.
