As an on your feet employee the chance of poor leg circulation is very high. Jobs that include prolonged standing are known to cause health problems including circulatory issues and lower limb and back problems.

On your feet 

Jobs in the health care, retail, hairdressing, and the restaurant industries (among others) require employees to stand for endless hours, and with unpredictable breaks because of the work environment. 

Work breaks are not the same for every industry, or within states either. State laws are mandated to have specific break times, but some companies opt to give employees the bare-minimum. This leaves employees on their feet longer. 

The Squat Break

Whenever possible revive your legs with some sort of exercise if you work in an on your feet industry. One of my favorites is what I call a "squat break. "

Take a bathroom break, and do one minute of squats. No one has to know, and it will help the circulation in your lower extremities. 

Do knee highs if you can't, or don't like squats. Do some sort of exercise after work to increase circulation if you can't squeeze in a squat break
