Question

explain the difficulties in evalution of office work

Answer 1

If you operate a small business, you may have a procedure in place to evaluate employee performance. An employee evaluation can be used as a way to determine if your employees should receive a raise or to provide them with feedback. If you conduct performance evaluations in your business or are considering implementing an evaluation process, you need to be aware of potential problems associated with them.Rater Bias

It's possible that the evaluator simply may not like the employee, which can influence how he rates the job performance. He may tend to focus on the negative aspects of the employee's performance while overlooking the positive achievements, intentionally or subconsciously, resulting in an unfair evaluation of the overall performance.
