The ultimate decisions on interpretations of the act are made by the
courts. The Administrator must determine in the first instance the
positions he will take in the enforcement of the Act. The regulations in
this part seek to inform the public of such positions. It should thus
provide a ``practical guide for employers and employees as to how the
office representing the public interest in its enforcement will seek to
apply it.'' (Skidmore v. Swift, 323 U.S. 134, 138 (1944).)
