What dose it mean to be a Hard working employee? please read the details below.

I see that a hardworking employee is the one who always achieve the agreed performance measures and strives to excced them to move on.

Excellent question! In my mind the modern hard working employee is someone who is engaged to his/her work and employer. Not a robot working24/7 nor someone who neglects family and friends because of the work, but a person who is flexible and in return the employer wants to be flexible.

A hard working employee is one who is committed to his work and timelines, is a smart worker in terms of finding innovation in the work he does and not merely doing it mechanically, is willing to challenge issues and tough situations and is a team spirited player

They don't work for show like staying late when the boss does or coming in early so that they are seen as hard workers. They just work hard and accomplish a lot as a result.

At the same time, they must create  a balance between official work and personal issues such as health and family.

To acheive good business, an employee and employeer both has to design a feasible and sustainable path to achieve company goals without damaging personal lifes.

Hard worker means, a committed professional capable of delivering Business Results in line with SMART (Specific, Measurable, Achievable, Relevant, Timebound) guidelines. Work-Life balance is extremely important. An energetic and satisfied employee always delivers the best results by spending time with family by taking care of his health and personal safety.   

Even having a passion to do something requires hard work. To prove to be a hardworker is an option of choice.
