Employers may fire their employees for misconduct, poor job performance, violating company policy(s), theft, damage to company property or the use of company materials for personal matters, insubordination, too many sick days without justification, or consistent lateness. Some employers may build moral clauses into their employment contracts, which hold employees to a certain standard in and outside the workplace. As such, social media activity that goes against these standards may be reason enough to fire an employee.
