If I understand the linked chart, there are discontinuities in the marginal tax rate, not the effective tax rate. So in that case yeah at certain levels the amount you owe on each additional dollar goes up, but that would not mean that making 105k is worse than 100k unless the marginal tax rate is greater than 100%.
This ignores stuff like losing childcare subsidies that is likely not included on the graph.
In the us you hear stories of people decreasing their income to be in a lower tax bracket and often it is due to them not understanding that the tax brackets are for marginal tax rates.
