EXCLUSIVE

A group of Wynn Las Vegas casino dealers are pissed they have to split their tips with casino workers who customarily don't get tipped ... and now they've filed suit to get what they feel they deserve. 

According to a lawsuit filed in federal court in Nevada, the dealers claim the casino forces them to pool their tips together ... but then share that pool with other casino employees.  

The suit claims the Wynn has effectively gotten around paying minimum wage by appropriating the dealers' tips.  

The dealers are suing the casino -- as well as Steve Wynn individually -- and are seeking damages, plus interest and attorneys' fees. 

We reached out to the Wynn for comment ... so far, no word back.
