Philip,
Thanks for your reply.

Is that the 'git log' log or internal logs? Are you sure? There doesn't appear to be a way to checkout that tip of see the log back from that tip.

So we will be unable to checkout content after a time?

The original branch is not 'destroyed', rather the pointer to the previous tip is within the logs. All the content is still available until the logs expire.

It's easy to misread some of Git's strengths if you have come from other historic corporate 'version control systems' which are often based on drawing office practice of old (e.g. the belief there is a single master to be protected is one misconception for software).
Rebase, at the personal level, is an important mechanism for staff to prepare better code and commit messages. Trying to hide the reality will just make your management 'control' less effective as staff work around it and delay check-ins, etc.
The broader access control and repo management issues are deliberately not part of Git, and there are good tools for that. e.g. Gitolite.
