What are the most common mistakes that cause you to lose your license or get fired in retail?

recently they had to let 2 techs go at the cvs that i work at. the techs were committing some type of fraud and this was ongoing for 2 months before they were finally caught. it raised a question for me: what are the most common mistakes that would lead to a retail pharmacist losing their license? what are common mistakes that can cause you to get fired in retail? i hope i don't have to come across losing a license in my career, or getting fired. ty in advance for the replies
