I’m always late. I’m literally late for everything. I don’t know why, exactly, but I think it has something to do with my overall terrible time management skills. I dramatically underestimate the time it takes to do just about anything, and even though this has been happening for literally my whole life, I seem unable to learn. Fortunately, I’m good at other things, and make a point of atoning for being late by being great at stuff. Also, I work for myself, which is good, because – surprise! — your boss doesn’t like it when you’re always late.

According to a new survey, regularly showing up late to work is frowned upon by most Canadian financial executives. The survey, conducted by Accountemps, found that 32% of these executives said workers should arrive on time, while 65% said coming in late on occasion isn’t a problem unless it becomes a pattern. Two percent of CFOs said they don’t care when you get to work as long as the work gets done on time.

Meanwhile, Accountemps conducted a separate survey of office workers in Canada to get their thoughts on the importance of showing up on time. Among the findings are that 56% of workers said they are occasionally late to work and 4% are late every day. And younger people are much more likely to be late; 55% of workers 55 and over are never late to work compared to 45% of respondents aged 35 to 54, and 28% of those aged 18 to 34.

Something else to consider is that one’s lateness may affect colleagues and their work performance. One-third of workers (33%) said that their productivity has suffered because a colleague arrived late to work.

Note that, if you’re the latecomer, this doesn’t just affect your coworker. This sort of ripple effect is also bad for your own career, and will likely impact your chances of getting a raise or promotion since that person is not going to protect you when the time comes to defend themselves and their own performance. Consider setting the alarm a bit earlier.

The survey also listed what they found to be strange or suspect excuses for lateness. These included:

Really? I’ll say that I don’t think getting pulled over for not wearing a seatbelt seems that suspect. Sure, maybe the person should have worn one.  But is it a weird excuse? And having to change after getting coffee spilled on oneself seems like a perfectly reasonable explanation to me. But what do I know? I’d also stay home if my dog was anxious, and I often think it’s Saturday.

Are these excuses that out there? Discuss!

“Punctuality is often perceived as a reflection of an employee’s work ethic,” said Dianne Hunnam-Jones, Canadian president of Accountemps. “Regularly coming to work late can give the impression that you’re disengaged, and leave colleagues and employers second-guessing your commitment.”

She added, “Tardiness also indicates a lack of respect for other people’s time, and can impact the productivity of coworkers who depend on you. If you’re going to be late, send an apologetic heads-up, and next time make it a point to be early.”

The gist of this is that you should try to be on time for things.

At least be punctual for the job interview, as 58% of hiring managers listed lateness as their top interview dealbreaker in a recent survey.

If you can’t always be on time, make up for it by being better than anyone else at absolutely everything. That usually works.

Gotta go. I’m late…
