Yelling at your boss is a sure way to get fired. My father told me before my first job decades ago. Go to work on time. Do your job , don’t get into other people’s business, say please and thank you. Be glad you have a job and a Check to cash every week, and put 25% of that in savings every week. He was a very wise man. He was a boss with at least 25 people working under him, who would he promote ? Yes .... the employee that came to work and did there job consistently.
