According to John Tschohl of the Service Quality Institute, retaining employees who perform poorly is expensive both financially and emotionally. It costs a lot of money to repair the damage they do.

This includes the time it take to correct mistakes they’ve made, dealing with a significant number of customer complaints, creating friction, and in-fighting. It also has an impact on morale and results in an increase in employee turnover.

There’s a term ranchers use when they are reducing the size of livestock by removing weak animals from the group. That term is ‘thinning the herd’. It could also be used in the workforce in relation to terminating non-performing employees, something most organisations don’t do nearly as often as they should.

High achievers — those employees who show up on time every day, work hard, and do more than is expected of them — won’t want to stay with you. They won’t respect you and will soon be heading out of the door to work for someone who doesn’t tolerate bad employees.

They notice when you give poor performing employees a pass and will start to question your ability to lead and to make good decisions. They will also resent you for relying on them to pick up the slack. You should do everything in your power to keep high-achieving employees.

Keeping employees who perform at substandard levels can also impact you personally and professionally. So, how do you go about letting those employees go? First, you must realise you can’t save them from themselves. They simply don’t care about their performance, you, or your company. Cut them loose.

Good managers can identify the negative traits of an employee within the first 30 days. That includes job knowledge, job fit, and performance. At year one, you should have a clear record of performance reviews. Take notes, document problems, and track corrective action. Make sure employees understand what is expected of them and why.

If you expect an employee to improve, both of you should understand what that improvement should look like. Schedule a time to review those expectations and benchmarks. If they haven’t been met, it’s termination time.

Firing someone can seem heartless at times but, actually, continuing to employ people who routinely fail is a disservice to them and to your organisation. On the positive side, it might serve as a wake up call to those employees and spur them on to improve their skills, their attitudes, and their performances.

It can take some time to recover and rebuild your team spirit after terminating bad employees. It can leave you feeling empty and exhausted, but you can turn things around by quickly getting back on track and doing whatever it takes to build a strong, cohesive team of employees who respect you for ‘thinning the herd’.
