Sickouts are commonly illegal. Though it is usually impossible to punish the individuals for calling in sick, an organization that promotes it - such as union - may suffer consequences, and organizing such thing may be a firing offense.

Proving it might be hard though and any organizing woudl be probably done by the full timers ie Union officers not activists.
