A bonus is subject to statutory deductions and the period of time you worked for the establishment. My employer promised a token of appreciation but... reneged on the promise. He opted for a bonus. Just express your concern to the person in charge. more

If your bonus is performance based, you should inquire as to how the bonuses are calculated. Are they subjective, objective or a combination.

It is hurtful I know but your salary payment was efficient as always that was bonus. My dear the job is scarce be vigilant with all the decisions... making for now. Check with your experience maybe it was your first year I don't know. more

It is hard to comment on your post because we are always biased in our favor. Assuming your comments are objective, you will not win any brownie... points by admitting you were looking at papers you were not supposed to.
The best approach might be to go see your boss, thank him for the bonus and by the way express your curiosity as to how the bonuses were calculated.
If your boss has a boss, his recommendations are probably reviewed. If his is the final word, your question may not be taken very kindly. Step gingerly. Good luck. more

I would ask how bonuses were determined and what you can do to increase the probability of achieving a higher bonus in the future. I would also have a... list of the impacts I made in the company to provide evidence that hopefully lines up with the criteria. I would ask for a specific rubric or criteria to ensure that you are working in alignment with the company's expectations and priorities so that you know how to manage your efforts and time. Let that determine how you proceed. I once had a staff of mine who thought his evaluation was unfair (it determined raises) and he requested a meeting to get more clarity. I was able to show him what high achievers' impacts looked like and he couldn't argue with the decision after that. It changed the way he showed up and I was happy to support him in getting to a high impact status in the organization.  more

Kindly go to your immediate manager kindly tell them you believe an error in calculation was made. Ask for a review. Don't mention pay of others

You Are Looking At This Emotionally, Not Logically. First issue I have is that you should never question a bonus nor should you be privy to what... others recieve for a bonus. You have no idea what their individual employment contract states for their tour of duty. I would however question your decision to question what was designated your portion of an imaginary bonus level. To much time spent on what others get means that time is not doing what you should be doing.
Maybe you are the reason your bonus is not sufficient and as a so-called professional, crying over your bonus is petty and a sign of immaturity. Bonuses are never guaranteed and having access to confidential employment records (which includes coworker bonus numbers) is a violation of company employment guidelines. Just do your job, be a leader and stop crying. This is the real world so your perception which is not based on facts will eventually cost you employment. Team Up! Not Poor Me Up!  more
