STUDY OF WORK EFFICIENCY DURING OVERTIME PERIODS

THIS STUDY WAS UNDERTAKEN TO OBTAIN INFORMATION RELATING TO THE EFFECT OF HOURS OF WORK ON WORK EFFICIENCY. MORE SPECIFICALLY IT WAS DESIRED TO LEARN WHAT EFFICIENCY COULD BE EXPECTED OF SNOWPLOW CREWS OPERATING IN OVERTIME PERIODS. THE STUDY PRODUCED CONSIDERABLE EVIDENCE RELATING TO HOURS OF WORK AND EFFICIENCY. HOWEVER, BECAUSE OF THE MANY DIRECT AND INDIRECT FACTORS INHERENTLY PRESENT IN WORK SITUATIONS (FOR EXAMPLE, THE HIGHLY IMPORTANT MOTIVATIONAL FACTOR PRESENT IN SNOW REMOVAL OPERATIONS), NO PRECISE QUANTITATIVE EVALUATION OF EXPECTED EFFICIENCY WAS DEEMED ADVISABLE OR POSSIBLE. THE DATA REVIEWED DID SEEM TO INDICATE THAT EVEN WITH CONSIDERABLE MOTIVATION, EFFICIENCY FALLS NOTICEABLY NEAR THE END OF THE SECOND SHIFT. CONTINUED DETERIORATION MAY BE EXPECTED ON THROUGH THE NIGHT WITH A SMALL RECOVERY POSSIBLE AT DAYLIGHT. BECAUSE OF THIS, AS WELL AS THE ADDED SAFETY HAZARDS PRESENT ON THE HIGHWAYS DURING STORMS, IT IS RECOMMENDED THAT THE WORK PERIOD BE LIMITED TO 16 HOURS EXCEPT IN EXTREME SITUATIONS. FURTHER, 2-HOUR PLOWING TOURS DURING PERIOD OF FALLING SNOW SEEM TO BE ADVISABLE, WITH A CHANCE GIVEN THE CREWS TO REST AND RELAX EITHER ON THE ROAD OR AT THE GARAGE. FINALLY, IF THE WORK PERIOD EXTENDS MUCH BEYOND 18 HOURS, IT IS RECOMMENDED THAT A CREW NOT BE ASSIGNED WORK IN THE NEXT 12 HOURS, AND PREFERABLY IT SHOULD BE HELD OFF UNTIL THE FOLLOWING DAY. THIS RECOMMENDATION WAS MADE BECAUSE THE DATA INDICATED THE LIKELIHOOD OF QUITE INEFFICIENT PERFORMANCE UNTIL THE CREW MEMBERS ARE THOROUGHLY RESTED.
