Do you think the one who leaves office on time is not a performer in comparison to one who is staying long?

Job performance is based on the adherence to the job descriptions not the amount of hours worked.

In any workplace, there applies unwritten work ethics, such as being at work on time, getting along with the team, projecting a positive attitude, and completing all assignments.

As a personal note, I prefer work quality over quantity. I pay you for 8 hours, I like to see you finish the work in 8 hours; if the assignment is too big for you to handle in that particular time frame, then that would reflect either on your knowledge of work assigned, or on my calculations of the time frame for assignment completion; either way, you should approach me to discuss it.

I discourage team members from spending any extra time at work; I encourage them to take all their time off, sick day and holidays. This practice boosts the team members’ moral, health and motivation, this boost is converted to company profits.

For me nop, its depending on situation.

Instance, i go home home on time not late due to all may works are done one time and all deadlines submission is submitted on time, management are not making issues. 

Some staff, stay late because they are not finish for their daily task.
