For that reason, I advise those who use this type of boards for the top of the workbench, to leave clearance in the holes of the rear screws, those on the side of the doors, and not to overtighten those screws to allow that slight movement of the wood. Otherwise, the board can become deformed by not having space to move. After a few months, the board stabilizes.
