The opposition insists they now deserve more than half the seats in the 15-member Cabinet. The bloc rejected an offer of four seats after the election.
The official Kuwait News Agency said the Cabinet approved an order by the country's ruler to suspend parliament sessions for a month. That extends into the holy month of Ramadan, an official holiday when parliament is typically shut down.
Earlier this month, Kuwait's labor minister resigned after opposition lawmakers threatened to question him on issues including rising food prices and alleged scandals over work permits. In May, the finance minister stepped down under similar pressures.
Kuwait was hit by a wave of strikes earlier this year, including walkouts that grounded the state carrier, Kuwait Airways, and temporarily closed customs posts and left hundreds trucks stranded at the border.
