DOVER, Del. — Democratic lawmakers have reintroduced legislation to increase Delaware’s current $8.25 minimum wage by $2 over four years despite a similar measure stalling in the General Assembly last year.

A bill introduced Thursday would increase the minimum wage in four 50-cent increments starting October 1 of this year, to $10.25 an hour in October 2020.

After 2020, the minimum wage would increase by a percentage equal to the cost-of-living adjustment under the federal Social Security Act.

A similar bill passed the Democrat-led Senate last year but stalled in the House after being roundly criticized by small business owners.

Supporters say an increase would help struggling low-wage earners. Opponents believe it would lead to businesses hiring fewer workers and passing on any wage increase to consumers, making goods and services more expensive.
