On site: Very flexible on the days you are at work, somewhat flexible on the hours you are at work on any given day, and generally supportive of flexibility, as well as having specific policies in place to support flexibility.
We work an extra hour every day to get every second Friday off, which is great. There is the extra overtime here and there but it really varies with roles.
Quite flexible depending on your needs
I work more hours than I should do. Company is somewhat flexible in work hours but it depends on the situations. South32 offers flexible work arrangements but it depends on what kind of work you do.
