The only thing worse than making a hiring mistake is not acting swiftly to correct the problem. Terminating an employee is a difficult decision, yet it needs to be a business decision, not an emotional decision. Here are three termination strategies:
Terminate the bad hire; then hire a replacement.
Hire a replacement discreetly; then terminate the bad hire.
Counsel out respectfully; allow them time to find a job while you search for a replacement.
