Can the public workers in Wisconsin recall the Wagner Act presently to coerce the governor to stop cutting collective bargaining in the state?

Congress enacted the Natl Labor Relations Act to regulate un ion relations with PRIVATE business. The States gave Congress nearly zero power over state employees when the States rstified the Constitution.

State relations with state and local employees are governed by STATE laws alone (and the Constitution, which makes no mention of unions). Wisconsin's rules for dealing with state and local employees are whatever the WI legislature enacts. Or repeals.

Many states OUTLAW state employee unions. Other states allow state employee unions, but limit their bargaining power. The feds lack any power to interfere.
