Libra makes a great team member, because you're able to keep your ego in check and work for the benefit of all. You also make a great leader.
Your sense of fair-play makes you a diplomat and a conciliator. Your bosses can trust you in situations which demand collaboration and cooperation. When someone's not pulling their share of the load, you can get them back on board with a few well-placed words.
But, because Libras are vulnerable to stress, they can be conflict averse. Even though you may not want to start a fight, you need to stand up to anyone not doing their fair share. Injustice is really painful for Libra natives, and you may regret it if you bite your tongue and say nothing.
