Yes. We use branches a lot at our startup. Typically our workflow goes as follows:

1) git checkout master

2) git pull // to fetch latest version

3) git branch issues/feature name

4) git checkout branch name

//...do work on branch...//

5) git add .

6) git commit -m "Description of commits"

7) repeat 5) and 6) until feature/issue is fully implemented/fixed

8) git push origin banch name

9) git checkout master

10) git merge branch name // only after the issue/feature is tested and debugged

11) git push origin master
