Well it shouldn't "jump about". The loads must be out of balance.
Even if it were a chipboard worktop and the top screws could have been fitted if it jumps about that much then the screws would have been torn out of the worktop anyway. Fix the feet down or the batten approach as suggested. But both of these are treating the symptom not the cause.
