From the point of view of a worker, the options of decreasing wages, working part-time, or a period of leave appear to be better options. In a logical system this would be true. However, our system is not logical. Employers cannot simply decrease wages, put people on part-time, or give them leave. The laws under which we live limit the options an employer may take.
Employers are constantly worried about being sued.
Often this fear constrains them and forces their hands to illogical options. I am not trying to defend the current system. I am simply pointing out what the current system is. A system where workers collectively endeavored and collectively owned their enterprise would be far superior to the existing system. Likewise, it would be uncommon for a worker in such a just system to bring suit against himself or herself.
