There are differences between countries though. E.g., in the US health insurance is not a taxable benefit, nor are a whole host of additional insurances:

transport passes, internet, phone services can all be tax free benefits.
Then there are also things like tax-free pension contributions, so if you have a cliff edge going form 0 to 45% tax you are much more liekly to try an max out your pension continue to get below the tax threshold. And then as you say, there is wokring hours and vacation. Iif you find that you have to pay early half your Friday afternoon's income in taxes you might just decide to stop working early and enjoy more free time.
Having lots of tax bands makes for a more stable system witho less unexpected events, e.g. when someone gets a payrise or a bonus and they are shocked to suddnely see nearly half dispear, instead with lots of tax bands the increase in amrginal tax is so gradual that people don't notice and don;t take action against that.
Rhis is the US marginal rates with 7 abnds:

Being the US it is missing a higher rate at the top but in general you see a nice smooth effective tax rate.
