When I worked for a cleaning company my partner started getting really sick, puking and the runs in the client's toilets while I did the rest of the house. (Thankfully the people weren't there.) She was sooo sick, and had a hot fever too. I called the office and told them that she was really sick and that I thought I should drive her home. They didn't care at all, and told her, "sorry, we can't get anyone to fill in for you," which was just an excuse of course, they had to cancel on clients lots of times for various reasons and it was never a big deal.
Although she cleaned the toilets really well after each time, imagine what the client would think if they knew that she was sick with a virus in their house, using their toilets?! Plus I had to work with her all day and could have caught it. At each house we went to she had to puke and poo in their toilets.
While I was working for that company I had a respiratory illness for about two months because I couldn't call in sick. Meanwhile we're in people's houses spreading our sick germs all over the place. Not a good idea if you ask me. For those of you who get housecleaning services, think about that one.
At one lady's apartment, I was training a new girl on her first day. Right in the middle of talking to the lady about what she wanted done, I got into this coughing fit so bad that I couldn't stop for about a full 15 minutes. I had to leave and stand out in the hallway, coughing my guts out and all this dark yellow stuff. It just wouldn't stop. I was humiliated. I'm surprised the lady didn't ask us to leave. And the new girl I was training quit the very next day. I think I traumatized her. Its a nasty story, and quite frankly I'm a little bit traumatized about it myself!
