Do people who work standing up have more varicose veins?

Although I am not working now, my previous job involved standing for more than half of the working hours.

Maybe even if I re-enter the workforce, I think I will do a similar job.

I have occasionally seen long-time professionals undergo varicose vein surgery; is this a kind of occupational disease that often occurs among people who work standing up?

I also tend to have swollen legs frequently, so I sometimes wonder if working for a long time might lead to varicose vein surgery. I'm curious if that's really the case. Of course, it probably varies from person to person.
