Seeking Advice: Salary Raise with Increased Commission Threshold

I’ve recently been earning a salary of £28k, with a commission structure that includes a £4k threshold and 30% on earnings beyond that. I’m currently training one associate and bringing in another, which has been going well.

I was excited to learn that I’m getting a pay raise to £30k, and when I reach an additional £50k in billing, it will increase to £32k. However, the company has also decided to raise my commission threshold from £4k to £5k, while maintaining the same 30% commission rate on earnings above that.

I’m concerned that while I’m being rewarded with a pay increase, I’m simultaneously losing an important motivational component of my compensation. With the new threshold, I end up losing approximately £300 due to the change (£1k – 30% = £300), and I’ll also have more responsibilities as I train two new juniors.

I’m considering asking the company to maintain my current commission structure instead. What do you think of this approach? Any advice would be greatly appreciated!
