How to improve QSR EBITDA with labor stability?

I hope there are entrepreneurs here who have at least one fast food restaurant and you could give me some tips on improving EBITDA. Right now our figures are not very high, but this needs to be solved somehow. Maybe the problem is staff turnover?

What is your current EBITDA? You have correctly noted the point about staff turnover, because before I was always looking for a solution to the problem of low EBITDA in a bunch of other points, and not in this. Then I read an article about how labor stability boosts EBITDA on the eb3.work website on the advice of a friend who is also an entrepreneur, and this finally made me understand that I was looking in the wrong place. I analyzed my current turnover, determined the cost of internships, then determined the ROI and started looking for ways for long-term employment of employees and decided to try the EB3 visa program.
