At your job, are you allowed any leeway with being late? If so, how often is it tolerated and what are the implications if it's not?

Are you allowed any leeway with being late? If so, is it on occasion or is it every day? How late? What happens if you’re not allowed to be late? Lecture, punishment, several strikes and you’re out? If you’re late, can you make it up or do you make it up by taking a shorter lunch, or does nobody care and your hours are very flexible?

I know some jobs don’t allow people to be one minute late, some allow employees to be late every day, some actually want people there early so when their shift starts, they’re ready to go. What about your job? Are they tolerant of lateness or not?
