This won’t be a popular post here, but when you have big corporations you invariably will have large unions. Unions started in United States over wages and working conditions. For anyone interested read about working conditions in the coal mines in Appalachia in the last century and in the the textile mills with child labor. Are some Unions corrupt - you betya, However, the nurses need a good union right now because they are arbitrarily scheduled on shifts, and many of the factories overseas that produce materials for US companies need some good unions.IMHO
Getting those unions under control is becoming a matter of financial survival, and if the private sector unions are going to be the union muscle in that fight then we either take them down too, or we get bled dry.
