Those areas run quite lean in most companies.

There is usually little excess to cut. In addition, HR is essential in the layoff process, and finance is often relied on as the financial status gets more scrutiny.

As such, these areas are rarely the source of major cuts in most layoffs.

More risky are the activities considered luxuries, like generous benefits and employee perks, and so on.

If you are involved in planning events, for example, those are some of the first things that companies cut when times get tight.

If, when times were flush, the company recently decided to explore new lines of business, or expand into new territories, those are tenuous places to work.

Unless the company is making a concerted effort to pivot entirely to these new areas, these kinds of new initiatives are often the first ones cut when times are leaner.

At the extreme end of the risk spectrum are contract employees. One of the main reasons companies use temporary or contract workers is for this very contingency.

Contract employees are usually the first out when the tide turns.

Beyond these areas, most jobs fall somewhere in between these poles.

Regardless of your layoff risk, keeping your résumé up-to-date is always good advice. You'd much rather have it and not need it, than need it and not have it.

Keeping your résumé current can help you not only weather the looming storm, but it will give you confidence that you can bounce back regardless of your layoff risk.

A good tool is to maintain a personal list of your accomplishments in a running document. Include major successes, and the essential summary information you might include when describing your job to an outsider. Update this list at least once a month to ensure that it's current and your memory of events is fresh.
