Demands?
How about a cap on executive pay? Maybe as some differential vs. the lowest paid employee. Call it 10×. If your lowest paid employee earns $50,000, nobody in the company can earn over $500,000 in total compensation.
A cap on wealth: anything over $1B in gross assets (including stocks, real estate, and other investments) is taxed at 100%. The revenue from this tax should be set aside to fund social safety net and small business development programs.
Now, with a large enough strike, the demands can get even broader:
All political campaigns must be funded by the national government. Each candidate who reaches some required threshold of support gets a grant. Individual donations may be accepted up to a defined cap, and business donations up to a separate cap. Each of these are publicly visible; business donations are individually listed, but individual donations are reported as a lump sum only. Donations must be kept in escrow accounts until the campaign officially accepts them. These caps can be set based on the 'size' of the election, given that a national election necessarily requires more resources than a local one.
All elections move to ranked choice.
