Given that potential employers spend only seconds on the initial scan of a CV, you don’t have long to impress.

What to include and what to ditch from your work experience is sometimes easy: that unpaid two-week stint at a tenuously relevant company over a decade ago can probably go; ditto anything written in Comic Sans.

However, there are some skills that not only do not add anything of worth to your CV, but reportedly could even have a negative effect on your finances.

Salary data company payscale.com has compiled a list of 25 skills that tend to correlate with lower pay, whatever your previous experience. The research, according to Time, zoned in on skills “that workers defined as being the most critical to their job” and within those, identified the 25 with the greatest negative correlation with salary.

And the skill with the worst effect on pay? Filing.

Many of the skills the company recommends deleting make sense because they’re ones any employer would assume of you anyway: typing, online research and the like. We all know how to google and we tend to use a keyboard to do it.

But others listed in the 2016 research seem stranger, such as plumbing, bookkeeping and customer service. One possible explanation could be that if you’re going for a job and have held positions in the past which obviously involve these skills, there’s no need to clutter your CV with the particulars.

There are also a number of specific computer programmes cited, such as Adobe Dreamweaver.
