Some jobs are just not worth the stress. Yes we all need money to survive and thrive but there can be ways to achieve that goal that will not leave you mentally baron. How many of us have looked around the office or state of work we are in and thought.... "Now this is too much?"
You know it's not a great place to work when employees band together to walk out. Literally.
Unions were basically created for this reason, by having the working people band together to fight against being mistreated by corporations, they create power in numbers. Even without a formal union, there is still power in numbers--no company wants to be tasked with explaining themselves like that.
