Does switching companies frequently a bad thing ?

Hi Folks, so one my friend tells me that if you keep changing jobs / companies as frequently as within a year or so it creates bad impact of us and the chances of getting hired by other companies are less.

Does this really effect on our resume or career? Does Hiring Managers check this as point before selecting any candidates ? Really wanna know as if we don’t switch we can’t survive in this companies for the salary they pay us.
