It may be tempted to stack vacation days over two work-weeks, but experts say that may be a bit too long to be away from your office. Sure, travel expenses are high and you want to stay on vacation longer to justify the cost, but worry or concern may set in putting a hamper on your vacation mindset.

You worry too much about returning

Your mind may wander after a week and wonder what’s going on in your absence and what you will encounter when you return, and that can be worrisome. Deborah Sweeney, CEO & Owner of MyCorporation, an online legal and business filing service, admits it’s difficult to take a two-week vacation.

“One of the biggest reasons not to take a two-week vacation is returning with a ton of stress because there is too much on your plate,” she says. “Even if you vacation for one full week and the two adjoining weekends, it can be manageable, but two full weeks is just too much and the stress begins to accumulate. The vacation becomes less enjoyable and relaxing.”

It may be challenging to get back to work

Being away from work for two weeks could put you at a disadvantage since you’ve been out of the loop for a period of time.

“Because it takes far too long to re-acclimate to your job the longer you are away, there will be a period of adjustment where you are less motivated and coming down from your vacation high,” says Roy Cohen, career coach and author of The Wall Street Professional’s Survival Guide. “Many of my clients claim that a long vacation may be beneficial to a recharge and a reboot but it wreaks havoc on their productivity.”

Your coworkers may be resentful

Some colleagues may be less than amenable to your leisurely vacation.

“If you are mid-stream on a project, taking a longer vacation will inevitably dump the heavy lifting on your colleagues,” says Cohen. “They may already have commitments and it is just not fair to them. And because it is your project, not theirs, they may be inclined to push it way down on their priority list.”

So, if they actually work on it, says Cohen, their diligence will be modest at best.

You can be out of the office less

If you take two weeks at a time, you may end up with a deficit should you need to take time off for an unexpected emergency, a medical matter, or just a day-to-day issue that will need to be addressed and which will take you out of the office. Says Cohen: “Spending too much time out of the office regardless as to why will soon label you as a lightweight and not a keeper by the company,” he adds.

Your worth could be impacted

If you’re away too long, people may find out they can get along without you, speculates Lois A. Krause, MBA, SPHR, SHRM-SCP, practice leader, HR Compliance with KardasLarson, LLC in Glastonbury, CT.

“You can look selfish and then may not be needed when you return. It could hurt your chances of moving up the ladder, or even retaining your position,” Krause says.

Furthermore, you can hear this feedback from coworkers that can only hamper your vacation mindset.

“Rumors and anxiety are increased exponentially by distance and time — don’t take that chance,” adds Krause.

Save the long vacation for something truly important

Two-week vacations, says Krause, should be only taken for special times, such as a wedding and honeymoon, a trip very far away, or a once in a lifetime trip.

“Otherwise, one week or less is enough to recharge and not leave your responsibilities to flounder,” Krause continues. “In today’s climate, organizations are lean and being away for too long can put undue stress on coworkers, subordinates, and yourself if you end up working harder before you leave and when you get back — it can erase one of the key benefits of a vacation: to recharge and come back stronger.”
