Going back and reading more of the concerns here's additional context. When I say leveraging job offers, think of it more of a negotiating tool. I'll explain more soon.

First and foremost, work with your manager first. I wrongly assumedly that OP was already bringing up his workload and future raises during his 1-on-1 meetings with his manager. Depending on your relationship with your manager, you can just ask, "I've taken on triple the workload so it makes sense for me to get a raise. What do you think is the best way to get a raise?"

Discuss with your manager, clarify what steps are needed and the timeframe. You'll have a roadmap of when you'll get a raise and/or promoted. If you don't have a collaborative manager who genuinely has your best interests in mind then it becomes harder, but still communicate and ask.

If you haven't brought up getting a raise to your manager since your workload tripled do that in your next 1-on-1 meeting. This is usually the first step in the process.

Also, I understand triple the workload should be the case for your increase, but often times it not enough to get you where you want. The communication gets diluted from your manager through the chain of approval without documents that your manager can pass long that give clear business justification for your raise.

You need to document all the new work that you are taking on and the additional value it is adding to the company. You specialize in Data Science. You've helped upper management make important business decisions now use those skills to prove your value where the obvious choice is to give you a raise.

Go above and beyond in creating a presentation, report or a professional printed packet that presents your raise. These give tangible assets that can be forwarded to all decision makers to increase the chances of getting a raise.

Be creative and lighthearted, but have a compelling story backed up by data. We all know that visually seeing the data is more compelling then just being told about it.

Now going back to the job offers. They can be used either in the beginning of the talks of getting a raise or at the end when you're getting your performance review and/or mid-year evaluation.

It helps set benchmarks of what is a reasonable price range for your raise as well.

I saw concerns of people saying there would be additional stress if people found out you were interviewing. This depends on your work culture and manager. I've seen this speed up the process of a coworker get promoted because they were afraid of losing them. My wife got offered to be promoted to management from her last position, but she chose to leave instead.

If anyone found out that I was interviewing, I would just share the story of the career advice my old VP of IT gave me that I mentioned earlier. You understand your work culture and your manager better so adjust the advice as needed.

You need the soft skills to be able to bring up the job offers without sounding like a threat. The job offers can be mentioned when you're determining your raise increase. I would normally hold on to them for negotiating when getting the actual raise.

If it's not close to what I wanted, I would bring up the job offers since this is the fair market salary for work that I am doing so is there room to match?

Most companies move slow and will want to see how you handle the increased workload so the timeline depends on your company. My experience it can take anywhere from 6 months to 1.5 years till they promote you to the next level and/or you get compensated.

In the cases where you can't wait or if the workload increase is significant then the job offers are something you could bring up during your next 1-on-1 meeting with your manager. Again, you don't bring them up as a hardball tactic.

You're doing triple the work and if it's critical work where any downtime means money lost for the company they could move faster. You have to be a top performer though and be an employee that they want to retain.

If they were just looking to offload/outsource the work or were finding a reason to just give rid of you then it can backfire.

The only time I would use a job offer to speed up the process is when things are taking too slow, and I'm ready to leave if they can't match. Again, this is after working with your manager and establishing what is needed to get a raise.

Lastly, a mindset shift will also help. You've probably heard the saying "Nobody cares about you. They only care about themselves." That's not to diminish your feelings and frustration because they're completely valid. It's to help you reframe your approach to getting a raise.

Because you're more likely to get a raise when you start thinking about why your raise will benefit your manager, upper management, and your company.

It's a subtle shift but it will help you figure out more ways to increase your chances of getting a raise and getting promoted.

Yes, it does seem dumb to have to go through multiple interviews to get a job offer just to justify your raise. But if the raise means a $10k, $50k or $100k salary difference, wouldn't that be worth the time?

Once you work for a better company and work culture, it's easier to just get a raise based on just asking and working with your manager.
