This is a management and leadership issue which impacts other staff members' lives and team morale. However, it's worth taking the opportunity to address it with the coworker individually before elevating it to leadership. There is something happening if leadership is not addressing it, as they would be alerted if they were chronically punching or signing in late. It may be that the time clock is a distance walk to the unit, or they stop at the cafeteria on the way for coffee and the result is they are late for their shift. It is not helpful to be passive-aggressive and complain to other staff members. Learn to have the uncomfortable conversation directly, kindly, and professionally with the person or people that need to hear it.
