Eventually, almost every business owner or decision-maker faces a familiar choice. Orders are piling up, business is steadily increasing, and you need more hands to handle the workload (unless you’re ready to turn customers and clients away, which most of us would rather not do). So which path should you choose: Hire a new person (or several), or simply pay your existing teams overtime and expect them to stay after standard working hours are over?

Of course, for some businesses, the decision makes itself. If you simply can’t expect your workers to stay late (because you know their personal schedules, public transportation, or the limits of workplace don’t allow that flexibility), you’ll need to let them go at five and hire a new pair of hands. And the same is true in reverse; if you know that it’s unreasonable to simply put the word out and attract hundreds of resumes from well-qualified candidates, you’ll have to work with the teams you have, end of statement.

But if either option seems reasonable, factor these metrics into your decision.

Crunch the numbers.

Sit with a calculator and make some assumptions. Assume you WILL, in fact, be able to find qualified candidates and bring them on board within three weeks. Assume you WILL be able to convince your teams to stay late and pick up some extra cash. Then run a comparison based on the period in which you expect to be swamped.

Take a look at that time period.

Are you dealing with a seasonal rush that will ebb as soon as the busy season ends? Or are you dealing with what appears to be steady and sustainable growth in your orders, deliveries, and invoices? If this looks like long term growth, save yourself some headaches and start your candidate search now. Find the very best available and invest serious resources in attracting them, onboarding them, training them and retaining them. This may mean ensuring that your salary offers are competitive.

On the other hand, if this is a seasonal rush, just keep a short-term view and cut costs where you can. Look for temporary helpers who can pitch in with minimal onboarding and training. Or of course, you can just cut the cost of hiring altogether and pay time and a half until the rush settles down in a month.

Anticipate problems.

New workers bring a social shake-up that can be somewhat unproductive—at first. Over the long term, the social fabric resettles and work returns to normal. But will you lose more money during that time than the contributions of the new hires are worth? Remember that new employees also come with necessary, but expensive, mistakes. The same can be said of overworked or tired employees who are pushed past their limits.

In the end, you’ll need to roll the dice but enter into the decision with as much data in hand as possible. For more on how to get the most out of your hiring resources, turn to the experts at Merritt.
