A group of immigrants decided to participate in a nationwide protest where immigrants refused to come to work. The boss told them to come to work, or they would be fired. They missed work, and were subsequently fired. Now they are complaining about it.
You don't get to decide when you want to work. If you don't like it, start your own business and see if your customers expect work to be done on time. You wanted to protest by showing your employer what a day without immigrants looks like. He responded by showing you what life without a job looks like.
