I’ve known a number of self labeled “liberals” that basically think being progressive means simply not being openly racist and restraining from yelling slurs on a street corner.
Surprise surprise it turns out they were just closet bigots who were aware what crowds they could get away with expressing their horrid views with and in the recent years figured street corners are now perfectly up for grabs.

If a “good boss” is being an actual good boss, the worst they should have to expect from the union is having the occasional friendly meeting with them to discuss any minor workplace concerns and contract negotiations.

Like you mentioned, this is an extremely common tactic used by religious leaders as well as cults. Back in the mid 20th century when the whole self help craze started, many cults took to framing themselves as self help groups to attract outsiders. NXIVM is probably the most infamous example of this. The first few meetings should seem like a normal support group but would soon start ramping up into full on cult mode.
