That said, for a lot of subcontractor trades, it's so hard to find anyone that I'd worry about the reverse: you get known as "the freaks with the cameras" and no one good bids on your stuff anymore, and then the delivery is even more delayed.
I think economists would call that a feature and not a bug. It is essentially an auction (something economists LOVE). You could instead take that money that you're spending on surveillance and instead spend it on giving the contractors a bonus to show up to your place instead.
I really don't buy that this would "shame" them into coming to your place first. Everyone already is aware that they don't always show up because you got out bid. You're "solving" the problem the wrong way because you're not addressing the actual problem.
That being said, as someone with digestion issues, tracking bathroom habits is offensive.
In short, yes this is invasive. But much like AI, this type of thing isn't going away, there is just going to be more lawsuits about it in the future.
Also, Unions hate this right?
For example, they can look back through yesterdays events to see that their plumber showed up - and then they'll know they need to go check on the work. The alternative is trying to get the plumber on the phone to figure out if the work had been completed or not - which is difficult in 2023.
There's not a lot of unioned workers in most states for residential construction. But autoworkers, and anything else in manufacturing would be used to the constant monitoring. Commercial construction also typically has fulltime site superintendents, who would do this anyway.
The GC can often bill it down to the homeowner as antitheft, which reduces time/money to complete the build. The biggest being time. An example, if custom windows are stolen, it could delay a project by months right now.
