Dutch authorities revealed errors in WIA payments, affecting long-term sick employees. Investigations found around forty-three thousand suspicious cases among two hundred twenty thousand files.

Errors led to both underpayments and overpayments between twenty twenty and twenty twenty-four.

Repayment processes will begin in September and continue detailed reviews until twenty twenty-seven. People overpaid will not need to repay, their benefits will be adjusted automatically.

Underpaid employees receive owed sums retroactively and have future payments corrected promptly. The government will not offer compensation; experts blame complexity for current miscalculations.
