[support] how can I add "view permission" to content being created?

Hi, I want to give to every user the possiblity to select view permissions (based on roles) for the content they create. I'm not sure I expressed myself correctly (I'm new to drupal) so I will make an example:

I have "anonymous", "authenticated", "customer" and "employee" roles. When some user of the "employee" role creates a story, he wants to decide which other roles will be allowed to see this particular content. This one might be e.g. only for "employee", next time he wants to create something for "employee" as well as "customer" or for all including "anonymous". How can I handle this?

I searched drupal web, found a lot of "*access*" modules and forum topics, but nothing suitable...
