If the operations of separate processors are integrated in producing
canned seafood products all employees of such processors who perform any
part of the described continuous series of operations to accomplish this
result would be ``employed in the canning of'' such products. Moreover,
preliminary operations performed in a separately owned processing
establishment which are directed toward the particular requirements of a
cannery pursuant to some definite arrangement between the operators of
the two establishments would generally appear to be integrated with the
cannery operations within the meaning of the above principles, so that
the employees engaged in the preliminary operations in the separate
establishment would be employed in ``canning'' within the meaning of
section 13(b)(4) of the Act. Whether or not integration exists in a
specific case of this general nature will depend, of course, upon all
the relevant facts and circumstances in such case.
