I’ve worked a few jobs in the past few years (all wide spread “chains”) only one that I worked for was not corrupt in some way (All the others verbally berated their employees, stole money from employees, stole money from charity, underpaid employees, etc…).
I live with my grandma(trying to move out while I’m in community college) and every time I’ve quit a job she’s always said that I either need to tell the manager why I quit or that I need to complain to corporate and tell them about the corruption going on.
I might just be too cynical however, I believe that most places would know about the corruption, and even if they didn’t they wouldn’t care about a lowly employee complaining about it. Instead they would probably just threaten legal action or something like that.
