The cabinet is traditionally a panel of advisers to the President. Times have changed somewhat, but the Cabinet still runs the departments of the executive branch and reflects the policies of the President. They serve at his will ; he can fire them if they do not perform.
A President and his cabinet meet and work closely together. The members of the cabinet will make suggestions and offer assistance in helping make the hard decisions.
Cabinet members can meet with the president, can discuss issues at cabinet meetings, and send memos to the president. The frequency of meetings depends on the president and the circumstances .
Cabinet members are appointed by the President; with Senate approval.
Members of the Cabinet were implicated in the Teapot Dome Scandal, but not the then President.

I admit I don't know if it is automatic, but I know it rarely happens. Given the relationship between a President and each of his/her Cabinet Members, it is logical to assume that the President will take care to pick people with whom he/she communicates well and perhaps even thinks like. If that is true, it would not be surprising for each new President to replace the Cabinet when he/she takes office. A new President has sometimes kept his predecessor's Cabinet, mostly in cases where the President was followed into the White House by his Vice President, and never in cases where the new President is of a different party. If I had to guess, I would say that by default, when the President goes, the Cabinet goes, so an incoming President would need to inform any members he/she wishes to keep on.
