Timber workers who convert trees into lumber, railroad ties, posts, piling, pulp for
            paper, mine timbers, shingles, etc., make up a large occupational field.

                     The occupational types range from the unskilled laborer to the professional.

                     Most problems arise because those who harvest the trees work under such varied conditions.

                     Harvesting occurs from the time timber workers select the trees for cutting, to the
                        point where the trees pass through the mill and become lumber, ties, posts, etc.

                     The work conditions and arrangements vary with the size of the operation.

                     Small operators usually exert more control over workers than big operators do.
                     
                     For example, one who buys or leases large stands of timber and operates a number of
                        mills to process them quite often subcontracts with others to complete certain phases
                        of the operation. However, the person who owns a single sawmill usually hires people
                        to do the work. The employer controls the workers and supervises the whole operation.
