Yes, many are, but apparently you don’t know of them.
And frankly, my saying you are clueless is a lot better than the alternative which is that you are completely lacking empathy.
And also selfish–what a thing to suggest, that I walk out on my colleagues at 5 o’clock on Friday and leave them doing my work late Friday night and Saturday.
I’m sorry notasheep, but you have no idea what the business world is like. It’s not such a crazy thing–if you aren’t exposed to it, why would you know?
