It may be regional, but Work Ethic is a major issue.
'Hire 10 to get 1 or 2 dependable worker's '. Seen that proven more times than I could count.
Dependability, punctuality, and a willingness to get the job done in a timely manor. (I'm not talking about regimented, assembly line type jobs. Although, I see
attendance issues there also)
Not being able to
connect with a co-worker for needed info or materials bogs down everything I'm doing as part of a team.
Vendors and suppliers that don't respond / repair things soonest. 'Its been down for over a week". 'We are waiting for an answer'. 'Payment Checks in the mail

'. And my pet peeve: Out sourced inventory ordering and restocking (Jobber only shows up on Wednesdays

)
