سازمان بین المللی کار در سال ۱۹۱۹ پس از پایان جنگ جهانی اول در زمانی که کنفرانس صلح در کاخ ورسای بر پا بود ، شکل گرفت . نیاز به پیـدایش چنین سازمانی در قرن نوزدهم به وسیله دو تن از صنعتگران ولزی و فرانسـوی یعنی رابرت اوون و دانیل  لگراند مورد تأکیـد و پیگیری قرار گرفته بود . پس از آنکه طرح مذکور در خلال همکاری های بین المللی جهت تدوین قانون کارگران در سال ۱۹۰۱ در باسل مورد توجه قرار گرفت . سازمان ILO  با هدف تدوین مقررات و قوانین بین المللی در جهت بهینه سازی  استانداردهای بین المللی کار و حصول اطمینان از بکار گیری آنها متولد شد.

   قانون ILO در بین ماههای ژانویه و آوریل ۱۹۱۹ به وسیله کمیسیون کار در کنفرانس بین المللی صلح تدوین شد . این کمیسیون ترکیبی بود از نمایندگان ۹ کشور بلژیک ، کوبا ، چکسلواکی ، فرانسه ، ایتالیا ، ژاپن ، لهستان ، برتانیا، و ایالات متحده آمریکا که رهبری کیسیون را ساموئل گامپرس، رئیس فدراسیون کارگری آمریکا ( AFL  )  بر عهده داشت . نتیجه این نشست بروز سازمان سه جانبه گرایی بود که تنها سازمانی بود که نمایندگان دولت ، کارفرمایان و کارگران را در یک نقطه سامان می داد . قانون ILO فصل هشتم معاهده صلح ورسای است .

   اولین نشست سالانه سازمان بین المللی کار ، همراه بود با دو نماینده از دولت و کارفرمایان و کارگران از هر کشور عضو که در تاریخ ۲۹ اکتبر ۱۹۱۹ با یکدیگر ملاقات کردند . این نشست مسائل مربوط به شش مبحث اول قانون بین المللی کار را که درباره ساعات کار در صنایع ، بیکاری ، حفاظت از زنان باردار ، ساعات کار شبانه زنان ، حداقل سن کار و کار شبانه برای جوانان در صنعت می باشد ، مشخص ساخت .

در بخش بدنه مدیریت اجرایی ILO که توسط کنفرانس انتخاب شدند ، نیمی از اعضا را نمایندگانی که از طریق دولت هایشان معرفی شده بودند ، یک چهارم آن را نمایندگان کارفرمایان تشکیل می دادند .آنها آلبرت توماس  را به عنوان اولین مدیرعامل دفتر بین المللی کار انتخاب کردند که دبیر کل دائمی سازمان بود . او یک سیاستمدار برجسته فرانسوی با اعتقادات راسخ و دغدغه های اجتماعی بود که در دوران جنگ جهانی اول  در دولت فرانسه مسئوولیت وزارتخانه مهمات را برعهده داشت . در همان آغاز کار ، اعتبار و قدرت خاصی به سازمان بخشید . در کمتر از دو سال ، ۱۶ قانون بین المللی کار و ۱۸ توصیه نامه تدوین شد .
