First of: Thanks for doing what you do comrade!
Try to contact the fine folks at the IWW, try to contact some of the already organizing labour campaings, have a look at the - not ideal, but somewhat useful - "No Shortcuts: Organizing for Power in the New Gilded Age" or an "Organizing for Power Seminar" i.e. Jane McAlvey's, something for the people after you that could be relevant are "bargaining unit seminars", too.
For help with contracts you need unions who already have contracts or political lawyers.
Remember that moving forward means to somewhat include the workers in your company.
If you have a contract don't exclude the right to strike during bargaining agreements for too long and/or include points for which you can strike even when an agreement is going on for points that weren't part of the previous ones (this is legally contested depending on where you are).
Have a meeting with your workers about what are the most pressing needs. Companies will try to low ball you, dare to say: "We can take your suggestions and talk with our workers about them" and if they walk back on things make that transparent.
Often the company tries to enforce discretion about what is discussed in those meetings, trots often argue that you ought to say no to that and talk with the full worker base about stuff. If this works is contingent on a lot of things. Why I write that is mostly to say: While the techniques used against you are often similar, the path you and your workers take is unique. More than what would be the perfect solution is the one that is done.
@CARCOSA@hexbear.net could we please feature/pin this post (maybe without federation people being able to see it even)?
