Which of the following did labor organizers believe was necessary, in order for industrial workers to gain wage increases?

mandatory union participation
government price controls
the right to bargain collectively
minimum wage laws

only answer if you re 100% right, you!

the right to bargain collectively

Explanation:

It is said that "there is strength in numbers". It is true. Once you have something powerful to offer, like a very significant strike that could stop a factory, it causes a much greater effect than a negotiation made by one employee who wants a raise and might skip work.

escalation means to increase in intensity, extent, or amount.

step-by-step explanation:

100%     = 120

1%= 120/100=   1.2

9%   = 1.2 x 9=     10.8

10.80 to the 120 to get $130.80
