Modern Slavery: How to Identify It and Key Legal Resources

When most people hear the word "slavery", they imagine historical chattel slavery systems formally abolished across most of the world by the 20th century. But according to 2023 data from the International Labour Organization (ILO), 50 million people globally are trapped in modern slavery on any given day – a 20% increase from 2016. This exploitation hides in plain sight: in local restaurants, neighborhood homes, agricultural fields, and the supply chains of common consumer goods. This guide breaks down clear signs of modern slavery, verified legal resources for reporting and survivor support, and safe steps to take if you suspect exploitation.

What Is Modern Slavery?#

The UN defines modern slavery as any exploitative situation a person cannot leave or refuse due to threats, violence, coercion, deception, or abuse of power. It includes six common, overlapping forms:

  • Forced labor: Work performed against a person’s will, under threat of penalty
  • Debt bondage: Forced labor to pay off a real or fabricated debt, often with exorbitant interest that makes repayment impossible
  • Human trafficking: Transport, recruitment, or harboring of people for exploitation, even if no national border is crossed
  • Domestic servitude: Unpaid or underpaid forced work in private homes, often hidden from public view
  • Forced marriage: Being married against one’s will, with no right to leave the union
  • Child slavery: Exploitation of anyone under 18 for labor, sexual exploitation, or forced criminal activity

Unlike historical chattel slavery, modern slavery is rarely formalized, which makes it harder to identify and prosecute.


7 Key Red Flags to Identify Modern Slavery#

Most cases of modern slavery share common warning signs you can spot in your community:

  1. Restricted freedom of movement The person is always accompanied by a handler when in public, cannot speak to strangers without supervision, or has their passport, ID, or immigration documents held by an employer or family member. For example: a domestic worker whose boss holds their work visa and refuses to let them leave the house alone.
  2. Abysmal living and working conditions Workers live in overcrowded, unsanitary shared housing (often on work premises), have no access to clean water, food, or medical care, and work 12+ hour days with no days off.
  3. No pay or unfair wage practices Wages are withheld entirely, or the worker is told their earnings go toward paying off recruitment fees, fines, or living costs. Many debt bondage victims earn less than $1 a day and can never pay off their supposed debt.
  4. Threats and abuse Workers report verbal, physical, or sexual abuse from employers, or say employers threaten to report them to immigration authorities, harm their family, or evict them if they complain.
  5. Social isolation The person has no contact with friends or family, does not speak the local language, and has no access to a phone or internet.
  6. Excessively controlling management Employers dictate what the person wears, who they interact with, and when they can leave work or residential premises.
  7. Underage workers in high-risk sectors Children under 18 are working in mining, construction, agriculture, domestic work, or commercial sex instead of attending school, and are exposed to dangerous working conditions.

Step-by-Step: What to Do If You Suspect Modern Slavery#

  1. Do not confront the exploiter or alert the person in front of their handler – this can put the survivor at extreme risk of violence, retaliation, or displacement.
  2. Document details safely: Note the location of the suspected exploitation, description of the exploiter and survivor, and specific red flags you observed, only if you can do so without being seen.
  3. Report immediately: Contact your national anti-trafficking hotline or local law enforcement if the person is in immediate danger. Most hotlines accept anonymous reports, so you do not need to share your personal information if you do not wish to.
  4. If you are a survivor: Reach out to your local hotline to access free, confidential support, including legal representation to pursue charges against your exploiter and access to compensation.

Frequently Asked Questions#

Q: Is modern slavery only a problem in low-income countries?#

A: No. The ILO reports 1 in 4 modern slavery victims are in high-income or upper-middle-income countries, working in agriculture, hospitality, domestic work, and construction. Exploitation also appears in global supply chains for consumer goods sold in wealthy nations.

Q: What is the difference between human trafficking and modern slavery?#

A: Human trafficking is a subset of modern slavery that involves recruiting, transporting, or harboring a person for exploitation. Modern slavery includes all forms of forced exploitation, even if the person never crossed a border or was formally "trafficked".

A: Nearly all countries have legal protections for good-faith reports of modern slavery. You will not face penalties if you report what you honestly believe to be exploitation.
