Does anyone know how long it usually takes the labor board to investigate a claim? Is there a number or a way to check on a claim's status? Thanks!

What kind of claim? A wage dispute?

If so, they vary in length depending on the amount of $$ claimed, the time frame in dispute and the Department's case load at the time.

In my experience, you should expect a minimum of three months.

When you filed your claim you should have gotten a letter back with a claim number. You can call NJDOL and give them the claim number and they can give you the status.

Good Luck!
