I think their more general point still stands, though; why would you expect a company trying to "sell" their employees to negotiate in the employees' best interests rather than that of the company itself?
That’s why in football there are 3 parties to a transfer deal: the two clubs and the player’s agent.
In a regular company trying to sell a whole chunk of workers, that should probably be a union. Which is indeed what happens in many European countries when this sort of thing happens.
I wouldn't... but I would expect the company trying to "buy" the employees to act at least partly in their interests - otherwise the new employees will soon become ex-employees!
