Answer:
Workers are hurt by unanticipated inflation (if wage rates are fixed.)
Lenders are hurt by unanticipated inflation
Explanation:
Inflation is a persistent rise in general price levels. Inflation is unanticipated if it is not expected to occur and it is not factored into the decisions made by economic agents.
Workers are hurt by unanticipated inflation (if wage rates are fixed.) For example, a worker earns $100 and the price of gasoline which the worker buys increases from $50 to $70 per litre. Due to the price increase, $100 buys less gasoline. The purchasing power of a worker with fixed income falls when there's unanticipated inflation.
Lenders are also at a disadvantage when there's unanticipated inflation. The value of money they receive at the end of lending period is less than the money they lent out.
