It really depends on where youelive, but I cansgive two pieces of advice:

1. Talk to your coworkers! Organizing is a bottom-up approach and organizers need to have the trust of their coworkers and listen like 80% of the time they’re organizing.
2. Search for already existing groups in your country that are actively helping folks organize! You’ll not be able to do this without help and a structured approach! A good first step is looking if the IWW (the Wobblies) are active in your country. They give organizing workshops.

Here’s a list of reading recommendations:

• Secrets of a Successful Organizer - hands-on guide on structured organizing.
• Raising Expectations (and Raising Hell) - Another guide. Basis for the “organizing for power” workshops the Rosa Luxemburg Stiftung carries out worldwide.
• Get on the Job and Organize - I think more of a collection of inspiring anecdotes. But I think it might be of value.

Edit: I want to stress how important a structured approach is for this. Doing it by intuition alone is very ineffective and might get you in trouble, once your bosses know what’s up.
