You omitted an important qualifier.
> assuming over course it doesn't cross legal or moral boundaries.
If someone asks me to clean the bathroom, sure I do it at home, much more rewarding to make $50 an hour, and probably less gross than the bathroom where a toddler is potty training.
As for the rest of those items although they may not explicitly fall under legal violations by US federal law, given the relationship between myself and my boss they probably cross policy lines and could be excluded under illegal. Except for taste testing food I'd do that one for sure.
But your framing this as a ruler and subject relationship is off the mark because every thing you listed has people that get paid to do exactly those things, that doesn't make them all serfs to a lordly managerial class.
It seems you have concocted the most absurd extreme interpretation of my words and then used that to refute my argument.
Ultimately I am willing to do pretty much whatever I am asked to as long as it is legal and moral, included in moral is my dignity as a human being.
Ultimately I feel that trying to frame every interaction with an employer as adversarial and feeling that everything is workers vs managers is immature and reductionist. At the end of the day Initech or Introde or whatever as a company doesn't really exist it is a legal fiction we use in society. What does exist is my boss my coworkers my customers. I want to treat them well and with respect and make life easier for them not because they deserve it, or because I think I will get ahead. I do it because I want to be a good person and good people treat others well even regardless of who they are.
It doesn't mean I need to be a door mat or allow myself to be exploited, but it means as an employee I try to behave like I would want my employees to behave if I were a manager, and if sometimes that means they ask me to do something for them that isn't inside of my regular job description I'll try and do that because I dont bave to come in and see Mr. Introde every day, I come in and see Dan my boss, or Carl the director and those are people.
Most everyone you meet is another person just trying to get by in the world and most people can really use someone cutting them some slack once in a while.
