This gets discussed as an identity question and it is really a market access question. Certain projects are effectively closed to one side or the other before the bid list is drawn, and that is what should drive the decision. Everything else — cost, workforce, administration — follows from which work you intend to chase.
In this article
Market access comes first
Some projects are effectively closed to one side before the bid list exists. Public work under a labor agreement, certain institutional owners, some large private developers — the decision is made before anyone reads your number.
So the first question is not which structure is better. It is which work you intend to bid over the next two years, and which of it your current structure closes off.
Why the cost argument misleads. Companies that go signatory to save money are usually disappointed. Companies that go signatory to reach work they could not bid usually are not. The decision is about the bid list, not the rate sheet.
What changes in cost
The hourly package is higher. The honest comparison is harder than the rate sheet suggests, because against it the open shop side should count wages plus payroll taxes, insurance, benefits offered, recruiting cost, training carried internally and the productivity loss from turnover.
Fully loaded, the gap narrows considerably and in some trades and markets it closes. What genuinely increases either way is administration: fringe reporting, contributions on schedule, and rules on apprentice ratios, overtime and work assignment that carry real consequences when missed.

Workforce availability
Sourcing changes fundamentally. You call the hall instead of recruiting, which solves staffing in busy periods and reduces control over who arrives.
Hall workers are generally trained to a consistent standard, which cuts supervision and rework. An open shop contractor with a stable long term crew often outperforms both. The variable that matters most is retention, not affiliation.
The middle paths
- Project specific agreements. Cover a single job without a permanent commitment. For a company that wants occasional access rather than a market shift, this is usually the right instrument and a far smaller decision.
- Separate entities. Legally intricate, examined closely, and not to be attempted without counsel experienced in labor law. Done properly they work; done casually they create serious exposure.
The questions that decide it
- What percentage of the work you want is closed to you today?
- Can you staff your current backlog reliably, or are you turning work away for lack of people?
- What is your actual fully loaded labor cost, including turnover and training?
- Do you have the administrative capacity for the reporting, or would you need to add it?
A contractor who can staff the work, is winning the bids he wants and has no administrative slack has no reason to change. One who loses bids before they are opened and cannot staff a busy summer has already been answered.

Frequently asked questions
What actually changes when a contractor becomes signatory?
Four things, and the administrative one surprises people most. Labor cost changes, though not always as much as expected once benefits and turnover are accounted for on the open shop side. Workforce sourcing changes fundamentally, because you call the hall rather than recruit, which solves staffing in busy periods and reduces control over who arrives. Administration increases substantially: fringe benefit reporting, contributions on defined schedules, and rules about apprentice ratios, overtime and work assignment that carry real consequences when missed. And the projects available to you change, which is the point — certain owners, certain public work and any project under a labor agreement become accessible. Companies that go signatory for cost reasons are usually disappointed. Companies that go signatory for access reasons usually are not.
Is union labor more expensive for a contractor?
The hourly package is higher, but the comparison is more complicated than the rate sheet suggests. Against the union package, an open shop contractor should count wages plus payroll taxes, insurance, whatever benefits are offered, recruiting cost, the training carried internally, and the productivity loss from turnover. When those are fully loaded, the gap narrows considerably and in some trades and markets it closes. There is also a productivity question that cuts both ways: hall workers are generally trained to a consistent standard, which reduces supervision and rework, while an open shop contractor with a stable long term crew often achieves better output than either. The honest answer is that the cost difference depends heavily on trade, region and how well a specific company retains people.
Can a contractor work both union and open shop?
There are structures that allow it, most commonly a separate entity arrangement, and they are legally intricate enough that they should not be attempted without counsel experienced in labor law. Done properly, separate entities let a company pursue both markets. Done casually, they create serious exposure, because the arrangements are examined closely and the tests applied are not obvious from the outside. There are also narrower tools for specific situations: project agreements that cover a single job without a permanent commitment, which is how many open shop contractors access work that would otherwise be closed to them. For a company that mostly wants occasional access to union projects rather than a market shift, a project specific agreement is usually the right instrument and a far smaller decision.
