Seeking Advice: Salary Increase with Higher Commission Threshold

I recently received a salary increase from £28,000 to £30,000, with the potential to reach £32,000 after billing an additional £50,000. Currently, my commission structure includes a threshold of £4,000, allowing me to earn 30% on anything above that.

I’m training one associate and bringing in another, so things are progressing positively. However, my company has proposed increasing my commission threshold to £5,000 while keeping the 30% commission for amounts billed beyond that.

I’m concerned that although I’ve been given a pay raise, the higher threshold might demotivate me. The change means I would effectively lose out financially, as the new structure would cost me an additional £300 in commission once I surpass the threshold.

With the added responsibilities of training two junior associates, I feel this adjustment doesn’t accurately reflect my contributions.

I’m contemplating approaching my employer to ask if I can retain my current commission structure. What do you think?
