A piece in today’s New York Post reminded us the importance of arriving to work on time.

That is, a woman who is a new hire for three months has been noticeably late at least once a week. Pointing out excuses about a tough commute or late bus, the boss doesn’t want to fire her but is in a bit of a quagmire. If everyone was late, the supervisor simply couldn’t run her shop.

The answer is simple so if you’re chronically tardy to the party (and by that, we really mean work), simply set an earlier alarm.

That said, Gregory Giangrande, chief human resources officer at Time, Inc. points out in the piece, “Sometimes, though, mornings can be a challenge when child care is an issue — school drop-offs or nannies’ schedules might require a daily beat-the-clock routine, and some employees may not want to raise that as an issue.”

Advising the boss to explore the problem further and evaluating to see if she’s worth keeping, he also suggests adjusting her schedule to start and end the day later.

So, our major take-away from his sage advice? Your job could be on the line if you continue to be tardy.

If she’s chronically late no matter what, he adds, “She’s out.”
