I can’t speak for Maryland, but in my state, the unemployment office decides how much unemployment money you should get based on your old job’s salary. This amount is less than your actual paycheck was, but it’s a decent percentage of your old check. Let’s call this smaller amount $x. The office doesn’t want to disincentivize you from working, so if you are able to find any work, permanent or temporary, unemployment will pay you $x minus the money you made that week.
If your state is anything like mine, be prepared for some serious disrespect; the unemployment office seems to assume that anyone who applies for unemployment is an able-bodied person who could get a job if they really wanted and is just trying to scam the system.
