I believe this type of issue is very common in workforce and I am not surprised. If one wants to convey his or her message across, then without arguing with the upper management, should plan an alternate way. There are many factors that affect one’s performance by going over the limits. For example, it can put his or her job with the company in a risk; also it affects the annual performance review of the employee. Managers or supervisors likes to keep even the smallest details in books and the employee should be careful when arguing with the management. On the other hand, employers should motivate the team and provide opportunity for growth. I believe this will be rewarded and appreciated by the employees.
