Can anyone explain what right to work laws are? along with any thoughts about unions. Do they actually benefit the worker and overall market?
For the googling part of your question:
In the context of US labor politics, "right-to-work laws" refers to state laws that prohibit union security agreements between companies and labor unions. Under these laws, employees in unionized workplaces are banned from negotiating contracts which require all members who benefit from the union contract to contribute to the costs of union representation.
According to the National Right to Work Legal Defense Foundation, right-to-work laws prohibit union security agreements, or agreements between employers and labor unions, that govern the extent to which an established union can require employees' membership, payment of union dues, or fees as a condition of employment, either before or after hiring. Right-to-work laws do not aim to provide general guarantee of employment to people seeking work, but rather are a government ban on contractual agreements between employers and union employees requiring workers to pay for the costs of union representation.
read on at Wikipedia.
For the second part, the thoughts about unions: this is very broad. Also it seems like you are trying to get someone else to write your homework for you? If not, it is still a broad subject and such a question is hard to answer in the SE format.
