The correct answer is B) Workers had to continue working in harsh conditions and for low wages.
The effect that anti-labor union laws such as the Combination Acts have on the working class was that workers had to continue working in harsh conditions and for low wages.
The Combination Acts of 1799 and 1880 did not authorize collective bargaining and trade unions. The British monarchy approved the first act on July 12, 1799. The government was afraid that workers would go on a strike or tried to force the government by any means to accept their demands. SO yes, workers had to continue working in harsh conditions and for low wages.
