You are a newly qualified radiographer working in a busy imaging department. Your contracted start time is 8:30 am.
Most mornings you arrive around 8:28, change quickly and are usually ready to begin work by 8:30.
One of your senior colleagues regularly arrives at 8:15. They use the extra time to change, make a coffee, catch up with colleagues and prepare for the day.
One morning they say: "People should really arrive early enough to be ready before their shift starts. It's just professional."
You leave wondering whether you're doing anything wrong.
