Background
: This study is how shiftworks among the socioeconomic factors is influenced on family function.

Methods : We have selected 237 shiftworkers group and 248 non-shiftworkers group in the industry and evaluated their family function by Olson's FACESⅢ.

Results : We compared the family function of shiftworkers with that of non-shiftworkers and then the results were below. In FACESⅢ cohesion of shiftworkers there were 59(24.8%) family in disengaged group and 80(33.7%) in separated and 62(26.1%) in connected and 36(15.1%) in enmeshed. In that of non-shiftworkers 52(20.9%) in disengaged and 70(28.2%) in separated and 73(29.4%) in connected and 53(21.4%) in enmeshed. In FACESⅢ adaptability of shiftworkers, there were 71(29.9%) family in rigid and 82(34.5%) in structured and 60(25.3%) in flexible and 24(10.1%) in chaotic. In that of non-shiftworkers 64(25.8%) in rigid and 84 (33.8%) instructured 65(26.2%) in flexible and 35(14.1%) in FACES III family types of shiftworkers there were 88(37.1%) family in balanced and 108(45.5%) in midrange and 41(17.2%) in extreme. In that of non-shiftworkers 88(35.4%) family in balanced and 116(46.7%) in midrange and 44(17.7%) in extreme.

Conclusion : In this resuls we found it out significant statistically that in shiftworkers there were more prevalent in disengaged and rigid family than that of non-shifftworkers and in non-shiftworkers there were more prevalent in enmeshed and chaotic family. In family types there were no significant differences in two groupes
