50/50 Employee

Do you have an employee that does some things really well but other things horrible? I call such employees 50/50.

Question, is it worth keeping such an employee on staff? Do employees like this provide value to a team or are they more trouble than they are worth?

Example, you have an employee that is a great technologist. When there is a fire he is the first one in and resolves the issue. When there are no fires, he struggles or most times does not provide the mundane information to monitor the environment. For example, documentation diagrams, KPIs, etc. So other employees have to pick up the slack.

There have been various methods used to tell this employee what is expected. From goal settings, to individual one-to-one meetings, to plain this is how it needs to be done. Yet very little improvement.

So this begs the question, does this employee’s value in a crisis outweigh his value overall to the team and department?
