Quitting allows you to leave on your own terms rather than being humiliated into training your low-pay replacements and then being fired. Are you really saying that workers should stick around at a company that was just days before trying to lay them off?
I don't think you understand something at play here. In my career of 28 years in IT, I have noticed that some people will just not leave - ever - under any circumstances until you turn out the lights and close the doors. What I mean is, no matter how bad the job is, some people will not ever leave it until they get thrown out the door or the company goes out of business. Not always, but usually it's the people who are just barely getting by. Some years ago we hired a guy who used to work for a local bank and his local bank got bought out by a much bigger bank out of state. They planned to shut down all their IT work in our city for this bank they bought, but they needed this guy and his co-workers to stay to help out with the transition. At first they were told 6 months and they'd be done. 6 months came and they got offered another 6 month extension. Then came another 6 month extension. The guy looked for another job and we hired him, but he left a co-worker behind who just didn't want to leave. Eventually after maybe 3 years, they finally closed down the IT work in our city and co-worker guy now for real has to find a job. The guy we hired asked us to hire his co-worker and we couldn't. No more openings. Even though this guy knew his job was going to end sooner rather than later, and the bank did not want to keep him on after it closed down all the local IT work they had, he refused to leave or even start looking for a job until they told him "Your job is over. Thanks. We'll send your final paycheck to you. Today is your last day." My previous employer, a European company, did some really reprehensible things to us before I left. They changed our terms of employment to favor them and enable them to cheat us out of severance pay they promised us and told us we had to either accept the new terms that let them do it or quit. Then they gave my small department 6 months notice that they were moving our jobs to another lower cost country (not India though). I was the only person in my office to find another job before the deadline. Nobody else would leave. One of the things you see at Disney is a lot of employees are big Disney fans, so they want to work there and they will put up with a lot of bs to do so. Even with these workers temporarily getting their jobs back, and yes we here all know this likely won't have a happy ending for them, more like a temporary reprieve, I guarantee you that many will still happily go back and refuse to look elsewhere for a job until they get this job taken away from them.
