Pay the fine, lay low for a bit and do it again. They also need to figure out a way so they can't hide behind the "subcontractor did it".
I'm talking about in general, not just construction sites, if people REALLY want change to happen, fine restaurants and put the owners in jail, you can't claim "subcontractor did it" at a restaurant, but I also don't want people complaining when their meal at a restauarnt is now $30.00 instead of $15.00, just like I don't want to hear any complaints when Avocados are $5.00 each and tomatoes are $5.00 a pound.
I have been an appraiser or appraiser traniee since Jan 2001, but I have also worked in restaurants/bars/hotels since 1990, what I have ALWAYS said is, the people who want everyone to "go back where they came from" is, that's fine, but when it happens, just DEAL with what happens after and do NOT complain when you get what you asked for. This is what people voted for, this what they will get, so accept it and be happy with whatever the results are and do NOT complain.
Here's an example, for YEARS I have heard people make comments when restaurant workers complain about LONG hours, working weekends, holidays, Sundays, no insurance provided or help with it, no vacation, for YEARS others would say, if restaurant workers don't like, they should find another job in another industry.
Well once COVID happend a lot of restaurant/bar workers did just that, they left the industry completely, now these same people making the comments before have changed to "no one wants to work" comments, they don't understand that a lot of people just "don't want to work" in certain work sectors and have moved on to something else. It's similar to the residential appraiser field, it's not that appraisers "don't want to work" appraisers just don't want to work in 2025 for fees that were common in 1994.
