Why were unions successful in the fight for worker's rights?

Unions were successful in the fight for worker's rights because they had better hours, and high money that they were being paid, and also a very safe condition for them.

Explanation:

At some point, workers began to revolt. They joined together and created unions in order to fight for safer conditions, better hours, and increased wages. It was easy for factory owners to replace one employee who complained, but much more difficult to replace all their employees if they went on strike together.

the protestant reformation's started in 1517, disturbing the religious and political order in europe´s catholic countries. the outcome was the european wars of religion prosecuted in europe in the 16th, 17th and part of the 18th century. nonetheless, uprisings, territorial disputes, and great power conflicts were also causes of the wars.
