Creating a strong team isn’t easy — no matter how strong your employees’ skills are, personalities clash. It’s your job to find a way to manage your employees, even the difficult ones. Here are three types of employees that are hard to work with and how to turn them into team players:

1. The suck-up

Every office has one: that one employee who’s only goal is impressing and garnering praise from the boss. They bring the boss coffee and offer to pick up his dry cleaning. Basically, they’re willing to do anything for a “good job,” except their actual job.

Co-workers of the suck-up are often annoyed, because they feel he is getting positive attention based on something other than the merit of his work. The rest of the team wants all the time and energy spent on flattering the boss to be diverted to getting quality work done.

As a manager, you have to show an apple-polisher that your recognition is not the most important type of acknowledgment. Take a look at your employee recognition program. Whose input affects the achievements that are most celebrated? Incorporate a peer-to-peer recognition program as a way to encourage suck-ups to consider the approval of their co-workers as well. Soon they’ll begin to realize that doing a good job and contributing to the team is appreciated by everyone, and that their peers’ praise can be as rewarding as yours.

2. The gossip

Not all forms of gossip are detrimental to a group. 2014 research from Stanford University found that groups that participated in gossip cooperated better due to higher levels of accountability. But when you have an employee that spends half of the day whispering about everyone’s weekend plans, you’ve got a problem.

Everyone is guilty of gossiping now and again, but “the office gossip” distracts the rest of her co-workers by constantly talking about others’ personal lives. Spreading rumors or deeply personal pieces of information can create tensions within a team.

The key to managing these types of employees is to redirect their social tendencies. Talkative people are social butterflies at heart. Give them projects that are geared towards creating interactions, like planning company retreats or holiday parties. These tasks will keep them busy — and keep them from distracting co-workers with unprofessional chatter. During these events, they’ll have an appropriate time to talk about non-business related topics and will be rewarded by seeing how their productive efforts have brought the team closer.

3. The underachiever

Sometimes you hire an employee that has a stellar resume and all the right experience, only to see him repeatedly perform below his potential. You were counting on him to act as an example for the rest of the team, but he just does the bare minimum on every task or project he’s responsible for every day.

Instead of being inspired by this anticipated high performer, other team members also begin to do less. Those employees that continue to go the extra mile resent the underachiever for having to pick up the slack.

If you’re confident that an employee has more to give, there’s a disconnect between you somewhere. Perhaps the actual day-to-day job he’s doing isn’t what he expected it’d be, or maybe he’s just bored. Talk to the underachiever to find out what he likes and what he doesn’t like about his job. Find out if he needs more challenging work to motivate him, or if he feels he’s not being given the opportunity to use his strongest skills. This will allow you to redefine his position so he can flourish like you always knew he could.
