In business, people often call the group that they work with (their company or department) a "team". For example, if a company wants to hire people to work for them, they'll put a link on their website which says:
Join our team.
Small companies also advertise the people that work there in a section on their website titled "Our Team".
You can name other departments or groups in your company by one of their members:
What's Becky's team working on these days?
And if you want to praise the people who work for you, you can say this:
We've got a fantastic team here.
