You are right but there are times when you may need to sack some people especially when they are not meeting up to your expectation. You just have to let them go if you want your business to grow.Sacking people is not good for sure. When adversity strikes, you need to find ways to overcome it rather than letting go of the good employees you have. You could even ask them to take a short break while you figure things out. Or reduce their earnings a little until you are earning enough to pay them well again.
