You accept this and continue. But now there is a new requirement that is looming ahead: you will have to clean the toilets as well! In addition to waiting on tables and washing dishes. And you remuneration is actually going to be less. Again, this is proposed as across the board industry standard.
Well, you dig your heels. You speak out against it. But what's the big deal, the management asks: you already washing the dishes, it's not a huge leap to cleaning the toilets from there. But it is! And you refuse to do it.
However, there are always people who (for various reasons) are absolutely desperate for money and they are prepared to do whatever to get it. So you find yourself in one camp and those people in the other. You never wanted this and you don't want to tell others how to live your life, but you like your job and don't want to quit it just because someone pushes something on you.
