Which Employee will show higher quality work?

B.

Having an employee showing high quality work needs the employer to provide the correct work platform.

This includes everything related to work process starting from the desk used by the employee, the ventilation system, the hygiene, the friendly work environment. On the other side, employees need to have latest technologies in hand to deliver quality work like latest pc, tablets, fastest internet connection. Moreover, employees need to have guidance in continous manner in order to stay motivated at work or else they would think that nobody cares if the work is done properly or not and with time they will become like zombies doing work with minimum effort needed.

It happens many times that managers keep to themselves the work accomplishments. Employees who present high work quality should be recognized by higher management.

Option B.

Option A is not really good. It's like giving someone a food and then asking them to throw it up if they're not good enough.

B

A.. One Who is given bonus after showing the good performance, and return back when the performance is not good

The one who will receive bonus after showing good performance

Obviously, Option B is right answer.  The company have to provide sufficient facilities and working environment to develop and reach their target. 

If the employee trusts the company, it will be B.

But really, I've never seen a company that pays bonuses in front.

The one who will receive bonus after showing good performance, because bonus should be offered as a reward, motivating employee to work harder, better and continuously.

offering bonus up front levels the work interest and may result in at most fair performances, as the employee becomes complacent and he's not really motivated to improve, and recolecting that bonus from him after the poor perfomances may induce him the feeling of unfairness, so he might migrate to competition.
