I bet it's actually easier to change the median. Often you'll scale a sales or support team (much lower cost than engineer) and these teams can often balloon especially if the company has a direct positive margin on their work (generally the case in sales). Now, 30% of the company is sales/support and there are quite a few options for outsourcing your sales team to a "professional sales company."

I created a salary distribution as an example, with 30% of employees at half the median pay, that get "outsourced":

1 1 1 2 2 2 2 3 6 60

median moves: 2 to 2 (+0%)

mean moves: 8 to 11 (+72%)

(You can make your own example.)

Usually, you expect the median to be pretty stable when you remove (or add) outliers. That's often the reason it's used in formal statistics.
