Everyone has that one friend who will happily tell you that, "Quitting my job was the best thing that ever happened to me!" And, while it is great for some, the fact of the matter is that everyone's situation is different and therefore it is not that simple for some people. Sure, there are a growing number of people out there who have found a much better quality of life after leaving a job they hated, but there are also a horrific number of people who simply cannot afford to leave their job else they face unsettling real-world consequences.
The challenges that many workers are facing in the workplace is a systematic issue that needs to be addressed. This is not a simple issue that will be solved by everyone just quitting their jobs; rather, we surely need to ensure workers are treated better from the ground up — with the result then being that workers are not feeling as though their job is grinding them into the very ground beneath their feet with no form of escape in the first place. Quitting your job may be the perfect thing for you (in which case, go for it), but that is sadly not an option for many.
No matter how well-meaning, people from positions of privilege thinking that the answer to so many people being unhappy at work is for those people to simply quit is ignorant, tone-deaf, and avoids them having to do any real thinking about how we fix the systems making those people, and so many more, unhappy in the first place.
