The survey found some correlation between absence rates and the blue-collar worker's attitudes toward the group they work with. Men's answers to different questions were classified under three headings; the individual's feeling that he's part of his crew and accepted as such; his belief that fellows in his group have "lots of team spirit"; and his conviction that "our crew is better than others at doing things." Everyone is a social being, and wants to feel he's accapted by his group and is included in all its activities, says Research Center.
