Now I see that these rooms are for merely harvesting for later use.
My next space was a larger space with a single private office. I gave the private office to my writer so she could conduct phone interviews away from the noise of the larger area. I supposed I could have booted her out if it was needed for lactation.
Maybe some enterprising individual can come up with a pop-up lactating room. Just checked...they already have these. Pods anyway. https://www.mamava.com ($11,250 and up). That company also has an inflatable one that rents for $250/day. That's not anything most small companies can afford for an occasional employee.
