In business, things cannot be done alone. No matter how intelligent or cunning you are, it is almost next to impossible to achieve excellence in business. There is a need for one to be in a team, or a collaborative effort. Too often, businessmen do joint ventures or tie-ups, whether with existing people in their team, or those outside their organization (for instance, a partnership with a supplier). This gives the impression that to succeed in business, you have to work in teams, lone ranger not necessary. Since you will be working in a team, it is important to know the qualities of a good team player. Come on, nobody wants to be with a Grinch or a spoilsport on a team! If you are to work in a team, at least you have to discover the traits necessary to become an effective team member.

Here are few tips to be a good team member :

• Communicate with your teammates respectfully. If you have ideas about how your team can reach your goal, share it.
• Use your active listening skill when you teammates are sharing their ideas and opinions. Remember to make comments and ask questions.
• Know that it’s OK not to be the leader. Being a good and supportive follower on a team is equally as important.
• Be reliable. You should be someone that your team can depend on to do their part of the task.
• Trust in your teammates to do their part. Don’t try to take on anyone else’s responsibilities unless they ask for help.
• Be kind and use manners when you’re interacting with teammates. Use the words “please”, “thank you”, and “Excuse me”.
• Compliment others on their strengths rather than talking about their weaknesses or what they’re doing wrong.
• If you need to give criticism, make sure that it is constructive. Constructive criticism is when you’re giving feedback in a kind way to help someone improve. Destructive criticism is when feedback is given in a way that hurts their feelings.
• Remain positive, even when things aren’t going well and you feel like quitting. When a team isn’t reaching its goal, it’s easy to start having a negative attitude. Negative attitudes usually makes things worse for the team. Be someone who motivates and encourages.
• Learn healthy ways of coping with anger and frustrations. Poor coping skills can keep you and your teammates from reaching your goals.
