We too have struggled with this issue. Damage to equipment,lost equipment, damaged customer property all adds up to major costs. Personally I would like to develop a program "point system" to award crew with minimal problems of this sort. Maybe include loss of "points" for valid customer complaints and poor performance. Would not want to reward bonus for people essientially doing their job, but maybe reward crews with prizes or a monetary bonus at end of season. Just have not taken time to develop.
