Most of what we do at work is not done by us alone. We work with others to complete tasks, give presentations and manage projects. As one of the ways to make sure I am giving credit where credit is due, I default to using we instead of I in most of my communication. By using we you can include your colleagues and you will create an air of partnership and inclusiveness that will make others appreciate the acknowledgement and excited to work with you. It is a small thing but quite noticeable to your team. If you are lucky, it might catch on and others on your team might start using it too.
