What is no straight in your statement is whether you were employed at the same time or your coworker was employed way before you were. It is possible... for your coworker to earn that kind of money if he was 1 outsourced, higher degree or more experienced and if has long service in that organization than you. more

This has nothing to do with trust. You accepted the payment terms offered to you at the time. The new employee accepted (negotiated) the terms for... their position. Times are different, more competitive, and salaries are higher. If you want more salary, ask if there are any advancement opportunities, take on more work, get more training. What your coworkers make should not be brought up.
Early in my career, I learned not to discuss salaries with my coworkers. I didn't and it made a more peaceful work environment. I'm sure that in some cases I made more, others I made less. I was also, willing to take on short term projects in addition to my daily tasks.  more

Am still digesting all responses, the coworker am of view that he should find time to reach out to HR and get guidance maybe even schedule for a... career progression and academic development for all workers , am sure this issue will best be addressed. Thanks  more

Did both of you start working at the same time? Consider the qualifications and experiences you have and compare them with your co-worker.

The fact that coworker eanrs more depends on whether government or profits organization. The measurable performance differs. We need to have... opportunities that are essential to improve global economy.  more

Yes, there’s something about your co-worker that you don’t have that warranties them that cheque. Look at how they run their work life versus how you... run yours then jaxtapose, otherwise both of you doing the same job doesn’t necessarily mean you should cheque the same. Good luck. more

Never ever ever trust your employer.

Twice is a lot of money for doing the same work. Not being racist or sexist, but what are we talking here? Are there any racial or male/female... differences? Maybe you’re just being silently being discriminated against.  more

It’s not about rebuilding trust. Your employer is not your friend and will do anything to squeeze out more productivity at a lower cost. What you can... do is address it or see if the competition pays better. A business is not a person and has no feelings or principles. It is designed to optimize its own economic performance. There is no space for trust or speculation, only hard facts and numbers.
That being said, if you literally work in the same position, this is of course unfair but corporate would never alert you to this because your loss is their benefit. So you can bring it up after having talked to the other person first to set the stage and test the waters.
It could be however that technically they hold a different position and earn more based on an additional responsibility you don’t know about yet. So it’s worth clarifying the details with your coworker before bringing this up to management.
The basic lessons here are:
1. Check the technicalities
2. Corporate will pay you as little as possible if you let them. They get bonuses for that.
3. There is no trust or loyalty in an average employment relationship. It’s purely business.  more

You made your Co- worker your competition Now fill n the gaps that you can show you added value and deserve compensation equal to the added value you... can provide or use that to research more opportunities in other fields your skills will be appreciated.  more

What are your opportunities in the job market? What salary offer do you think to receive from outside? These answers are influencing your negotiating... power. Without this information you can go to a war without weapons. more

Yes, trust can be rebuilt, but it depends on how management responds after the issue is raised. Discovering that a coworker earns significantly more... for essentially the same job can feel discouraging and may damage confidence in the organisation. Rather than assuming bad faith, I would request a professional conversation with my manager to better understand how pay decisions are made, whether there are differences in responsibilities, experience, or performance expectations, and whether my compensation can be reviewed. If management is transparent, listens to my concerns, and takes fair steps to address any genuine inequity, trust can gradually be restored. However, if concerns are dismissed or there is no willingness to explain or correct an unfair situation, rebuilding trust becomes much more difficult." more

Me too of recent I found out my coworker less qualified than iam, earning more than me yet what I do he has never done it perfectly, the duties and... so forth...but I gave it a deaf ear, since maybe he has spent too much time in the company than i..maybe that's y but it truly pains more

The period you started work can determine, also the incentives attached due to some specialties.

It's called Negotiating power

Does your coworker have a higher degree, more experience, or have worked there longer than you?

ask them for a raise but do not mention that you know about your coworker
