You’ve got forty employees. A small restaurant group, two locations, doing solid business. Your managers are good people. They work hard, they care about the food, and they’d never intentionally screw anyone over on their paycheck.

But here’s the thing: for the last eighteen months, your kitchen prep staff have been clocking in at 9:00 AM and starting work at 8:45. Just fifteen minutes. Setting up their stations, sharpening knives, getting the mise en place ready. Nobody asked them to clock in early. Nobody told them not to. It just... happens.

Fifteen minutes a day. Five days a week. Forty employees. Eighteen months.

That’s roughly 23,400 hours of unpaid work. At New York minimum wage, you’re looking at a base liability north of $375,000. Double it for liquidated damages. Add attorney’s fees. You’re staring down three quarters of a million dollars.

For fifteen minutes.

Welcome to the lawsuit magnet. The HR mistake that doesn’t look like a mistake until a plaintiff’s attorney does the math.

Before we get into the mistakes themselves, let’s talk about why class actions are a different animal entirely.

When one employee sues you for unpaid overtime, that’s a problem. A real one. But it’s a contained problem. You settle for the wages owed, maybe some liquidated damages, and you fix the issue going forward.

When forty employees sue you for the same unpaid overtime? That’s a class action. And it changes everything.

Here’s the critical distinction most employers miss: there are two different types of multi-plaintiff lawsuits, and they work very differently.

FLSA Collective Actions operate on an “opt-in” basis. Under federal law, employees who want to join the case must affirmatively sign written consent forms. The statute of limitations keeps running for each individual until they opt in. This means some employees may time out before they ever join. It’s still bad, but there’s a natural limiting factor.

State Law Class Actions under New York Labor Law Section 190(3)? Those are “opt-out.” Every employee who falls within the class definition is automatically included unless they affirmatively request exclusion. They don’t need to sign anything. They don’t even need to know the lawsuit exists. They’re in.

And here’s what makes New York a plaintiff attorney’s playground: you can file both at the same time. A hybrid FLSA collective action paired with an NYLL class action. Federal claims running parallel to state claims. Different rules, different damages, same set of facts.

This is the concept that keeps me up at night. Not because it’s complicated, but because it’s so simple and so few employers understand it until it’s too late.

The multiplier effect works like this: Take a single violation. Something small. Missing a meal break documentation requirement. Not paying for five minutes of pre-shift work. Calculating overtime on base pay instead of the regular rate.

Now multiply it.

Number of affected employees. Times the number of weeks the violation occurred. Times the per-incident damages. Times liquidated damages (which doubles it under both federal and state law). Plus attorney’s fees.

Let me give you a real-world math problem.

Say you have 30 tipped servers, and you’ve been miscalculating their overtime rate for two years. Instead of using the regular rate of pay (base wage plus tips), you’ve been calculating overtime on the tipped minimum wage alone. The average underpayment is $45 per week per server.

Here’s the math: 30 employees times 104 weeks times $45 equals $140,400 in unpaid wages. Double it for liquidated damages: $280,800. Attorney’s fees typically add another 25 to 33 percent: roughly $70,000 to $93,000.

Total exposure: approximately $351,000 to $374,000. For a math error.

And it’s getting worse. According to data tracked by other employment law firms, FLSA collective action filings have risen over 400 percent since 2000. The top ten wage and hour class action settlements totaled over $614 million in 2024 alone. That included a $233 million Disney settlement and a $72.5 million Home Depot settlement, among others.

New York is ground zero. The Southern and Eastern Districts of New York consistently see more FLSA filings than any other federal courts in the country. If you’re operating a business in the five boroughs, on Long Island, or in the Hudson Valley, you’re litigating in the most plaintiff-friendly wage and hour jurisdiction in America.

These numbers aren’t hypothetical. This is where the industry is.

Every plaintiff attorney I’ve ever dealt with, on either side of the table, evaluates the same factors when deciding whether to take a case. They’re looking for class size (at least 30 affected employees), commonality (one policy, or one mistake, applied uniformly), and per-employee damages high enough to justify the litigation.

Here are the six mistakes (all ficticious, yet based on real world facts) that check all three boxes.

This is the single most common source of wage and hour collective actions. And it’s the one that sneaks up on employers the fastest.

Off-the-clock work includes any time an employee performs work-related tasks without compensation. Pre-shift prep. Post-shift cleanup. Answering work emails after hours. Attending mandatory meetings without pay. Putting on required uniforms or safety equipment before clocking in.

The FLSA is clear: if you know or should have known the employee was working, you owe them for that time. “But I didn’t ask them to work early” is not a defense. “But nobody told me they were staying late” is not a defense. If it’s happening and you’re not stopping it, you’re endorsing it.

Walmart learned this lesson to the tune of $640 million. In December 2008, the company announced the settlement of 63 wage and hour lawsuits filed across 42 states for off-the-clock work, missed meal breaks, and related violations. That settlement came on top of a $172 million jury verdict in California and a $78 million verdict in Pennsylvania in earlier cases. One company. One type of mistake. Hundreds of millions of dollars.

We covered this issue in depth in Off-the-Clock Overtime: When “Quick Questions” Cost You Big. If your managers are texting employees after hours, if your kitchen staff is prepping before they clock in, or if anyone is doing work on your behalf without getting paid, that article is required reading.

This one comes in two flavors, and both are devastating.

Exempt vs. Non-Exempt Misclassification. You’re paying someone a salary, so you assume they’re exempt from overtime. But the FLSA doesn’t care about salary alone. To be exempt, an employee must meet specific duties tests for executive, administrative, or professional exemptions. The job title doesn’t matter. The actual duties do.

That “Assistant Manager” who spends 80 percent of her time on the register and 20 percent on scheduling? She’s probably not exempt. That “Director of Operations” who mostly delivers food? Almost certainly not exempt. And every hour of overtime they’ve worked without premium pay is now owed, with interest and liquidated damages.

We’ve broken down the exempt classification trap in detail: The Salary Myth: Why Paying Someone Salary Doesn’t Make Them Exempt and Classification Crisis: How to Audit and Fix Exempt Employee Mistakes.

Employee vs. Independent Contractor. You’ve got delivery drivers, cleaning crews, or consultants that you’re paying as 1099 contractors. If they work set schedules, use your equipment, and can’t work for competitors, they’re employees in all but paperwork. The IRS, the Department of Labor, and the New York Attorney General all have opinions about this, and none of those opinions are in your favor.

FedEx learned this the hard way, settling independent contractor misclassification claims for $240 million in 2016 covering drivers in 20 states. Studies estimate that 10 to 30 percent of employers misclassify at least some workers. And here’s the thing that gets lost in the big headlines: the same rules that nailed FedEx apply to every business. Your two-location restaurant. Your family-run cleaning company. Your mom-and-pop delivery service. You don’t get a size exemption. You are a target no matter how small your operation.

Different consequences for similar violations. It sounds like bad management. In court, it sounds like discrimination.

When Employee A gets a verbal warning for tardiness and Employee B gets terminated for the same thing, the question isn’t whether you had a good reason for the difference. The question is whether Employee B is a different race, age, gender, or disability status than Employee A. Because if they are, you’ve just handed a plaintiff’s attorney the single most powerful piece of evidence in a discrimination case.

Inconsistency is the hallmark of discriminatory intent. Not because it proves you intended to discriminate. But because it creates an inference that something other than the stated reason was driving the decision. And once that inference exists, the burden shifts to you to prove a legitimate, non-discriminatory explanation.

Good luck doing that when your documentation is a verbal warning that was never written down and a termination memo that doesn’t reference any prior discipline.

Pattern-and-practice discrimination claims take this to the next level. These allege that discrimination isn’t an isolated incident but the employer’s “standard operating procedure.” Statistical evidence showing that discipline, promotion, or termination decisions disproportionately affect a protected class creates a rebuttable presumption that every employment decision during the violation period was discriminatory.

The EEOC can bring these claims. So can private plaintiffs as class actions. And the damages include compensatory damages, back pay, front pay, punitive damages under the New York Human Rights Law, and attorney’s fees.

We’ve covered how documentation failures fuel discrimination claims in Performance Anxiety: Undocumented Coaching and Discipline Disasters: What Happens When You Skip the Paper Trail. If your discipline practices look different depending on who’s sitting across the desk, those articles are your starting point.

No written attendance policy. No written progressive discipline policy. No written anti-harassment policy. No written complaint procedure.

When you don’t have written policies, every decision becomes ad hoc. And ad hoc decisions, by definition, are inconsistent. Which brings us right back to Lawsuit Magnet #3.

But missing policies create problems that go far beyond inconsistency. In harassment and discrimination cases, a written anti-harassment policy with a complaint procedure is the foundation of the Faragher-Ellerth affirmative defense. Without it, you lose one of the most powerful legal shields available to employers. The defense requires proving that (1) you exercised reasonable care to prevent and correct harassment, and (2) the employee unreasonably failed to use the complaint procedures you provided. No written policy? No complaint procedure? You can’t prove either element. Defense gone.

And in class actions specifically, the absence of written policies is often what creates commonality: the single shared condition that ties all plaintiffs together. A plaintiff’s attorney doesn’t need to prove that every employee was treated identically. They need to prove that the same gap in your policies affected all of them. “No written discipline policy across all four locations” is exactly the kind of company-wide deficiency that certifies a class.

Written policies also serve as the foundation for your training program. No written policies means no training on policies. No training means no defense when an employee claims they didn’t know the rules. And no training records means the DOL, the EEOC, and every plaintiff’s attorney in the five boroughs assumes training never happened.

If you’re in hospitality, this is the big one.

The FLSA allows employers to take a tip credit, paying tipped employees a lower base wage as long as their tips bring them to or above the full minimum wage. But the rules around tip credits are precise, technical, and absolutely unforgiving when you get them wrong.

First, you must provide written notice of the tip credit before you apply it. Every time. For every tipped employee. A missing notice doesn’t just create a paperwork problem. It invalidates the entire tip credit for that employee, meaning you owe back the difference between the tipped wage and the full minimum wage for every hour they’ve ever worked.

Second, managers and supervisors cannot participate in tip pools. Period. Employers are expressly prohibited from allowing managers or supervisors to share in tips. The shift leader who “helps out” behind the bar and takes a cut of the tip pool? That’s a violation. And it affects every employee in the pool, every shift it happens.

Third, the side work rules. Under New York’s Hospitality Wage Order, tipped employees can’t spend more than 20 percent of their time or more than two consecutive hours on non-tipped side work while receiving the tip credit. Both limits apply independently. Violate either one, and you lose the tip credit for that shift. Not just for that employee. For every employee in the tip pool. Everyone.

Now multiply that across every tipped employee, every shift, every week. That’s the class action.

This is the mistake that makes all the other mistakes worse. And in New York, it’s the one that sets a floor on your liability before you’ve even gotten to the substance of the complaint.

New York requires employers to maintain payroll and time records for six years. Federal law says three, but if you’re in New York, the state wins. And “maintain” doesn’t mean “probably have somewhere on an old computer.” It means accessible, organized, and producible on demand.

When the DOL requests your records and you can’t produce them, the burden of proof shifts. Instead of the employee proving they were underpaid, you have to prove they weren’t. That’s a reversal that changes the entire dynamics of the case.

But here’s where it gets really expensive. The New York Wage Theft Prevention Act requires employers to provide written wage notices to every employee within five business days of hire, and accurate pay stubs with every payment. The penalties for non-compliance are staggering, and plaintiff attorneys know it.

Here’s the math that keeps employment lawyers in business. If you failed to provide the required wage notice under the WTPA: $5,000 per employee in statutory damages, plus liquidated damages, plus attorney’s fees. That covers the last six years under New York’s statute of limitations. Before you even get to the question of whether the employee was paid correctly, your floor is $10,000 per employee.

Now assume the employee was also underpaid. That amount gets doubled for liquidated damages. And because you paid them wrong, their pay stubs are also wrong, which triggers the second half of the WTPA: another $5,000 per employee for inaccurate wage statements, plus liquidated damages. Your floor just jumped to $20,000 per employee. Plus attorney’s fees.

Multiply that by 40 employees and you’re looking at $800,000 before anyone calculates the actual underpayment. This is why a great number of class actions in New York are premised on the failure to strictly comply with the WTPA alone. It’s not because the wage notice is the most important document in your HR file. It’s because the penalty structure makes it the most expensive document you never provided.

We’ve covered WTPA compliance in depth: Show Me the Money (Correctly): Mastering NY’s Wage Statement & Notice Rules and The Paperwork Trap: How Missing Wage Notices Turn Bad Pay Practices Into Catastrophic Liability. If you haven’t read those yet, they explain exactly how the WTPA turns a paperwork oversight into a six-figure minimum.

And it’s not just payroll records. Missing training sign-in sheets mean you can’t prove training happened. Missing investigation files mean you can’t prove complaints were addressed. Missing performance documentation means you can’t prove the termination was legitimate.

The golden rule of employment law documentation: if it’s not written down, it didn’t happen. In a class action, that rule gets exponentially more expensive. Because it’s not one missing file. It’s forty missing files. Or a hundred.

Every class action I’ve ever seen started the same way. Not with a conspiracy. Not with a deliberate plan to cheat employees. It started with a shortcut. A “we’ll fix it later.” A “that’s how we’ve always done it.”

The fifteen minutes of pre-shift work that nobody tracked. The overtime calculation that was close enough. The tip pool that included the shift lead because she’s technically not a manager, right?

Small decisions. Made quickly. Repeated daily. Until the math catches up.

The difference between a $12,500 compliance investment and a multi-million-dollar settlement isn’t knowledge. Most employers know they should be tracking time accurately and classifying employees correctly. The difference is action. The willingness to stop, audit what you’re doing, and fix what’s broken before someone else finds it for you.

Plaintiff attorneys aren’t looking for evil employers. They’re looking for patterns. Consistent, systematic, well-documented patterns of violations that affect enough employees to justify the litigation. Your job is to make sure those patterns don’t exist.

Do the audit. Fix the math. Train your managers. And build the paper trail that proves you did it right.

Keep fighting the good fight.
