I recently read about a union effort in Amazon and a photo of an Amazon flyer was mentioning that accepting a union at Amazon means paying for it:

I am French and do not know how unions work in the US, so apologies if the question is obvious: are all employees of a company automatically paying for a union once there is one in the company?
By "paying", I mean "having an entry on the payslip with "union fees"".
I can imagine that there are some indirect payments possible (the company must co-pay for the union, and this may ultimately mean that the salaries are lower (this is an extreme example)), or that some employees want to join the union (and pay their fees).
The flyer seems to suggest however that once a union is formed, everyone must pay for it. Is that correct?
