What Being a Union Shop Means for Every Plumber Linek Sends to Your Home

Linek Plumbing Company is a union shop. Our plumbers are members of Plumbers & Pipefitters Local 562, the United Association local that covers the Saint Louis area. Below is what that membership actually requires: the training, the pay structure, and who ends up in your home. Missouri’s plumbing licensing rules add one more reason this matters here specifically, and we’ll get to that too.

The Short Version

Linek Plumbing is signatory to UA Local 562. This means our plumbers are union members, not independent contractors or subs pulled in for the day. Entering the union requires a five-year apprenticeship with a set number of paid training hours each year. It also requires a journeyman-level test and ongoing continuing education. Union plumbers are also paid hourly, not by commission, which changes what the person standing in your kitchen is actually there to do. In Missouri, plumbers are not licensed at the state level. Therefore, union training substitutes for a state licensing board. That’s one more reason the union credential carries weight here.

What Does It Mean That Linek Plumbing Is a Union Shop?

Our plumbers are members of a labor union, specifically UA Local 562, the Plumbers & Pipefitters local that represents around 4,500 workers across 67 counties in Eastern Missouri. When Linek hires a plumber, that person joins Local 562. They work under the wage, training, and benefit structure the union and its signatory contractors have agreed to. Linek does not set this structure on its own.

That’s different from a company that calls itself “union-friendly” or hires non-union labor for some jobs and union labor for others. Every plumber Linek sends to a residential call went through the same union apprenticeship and carries the same union credential. You’re not getting a mix of in-house staff and day-labor subcontractors depending on how busy the week is.

It’s also part of a company history that goes back further than the union credential itself. Linek Plumbing has served the St. Louis area since 1916, and we have always prioritized union-trained expertise built over generations, not one crew’s reputation.

What Is UA Local 562?

UA Local 562 is the local chapter of the United Association, the national union representing plumbers, pipefitters, and related trades since 1889. Local 562 covers plumbers, pipefitters, and several related trade groups across Eastern Missouri, and it runs its own training center in Earth City, apart from any single contractor.

Local unions like 562 exist so training, testing, and wage standards don’t have to be reinvented by every plumbing company on its own. A contractor that’s “signatory” to the local, like Linek, agrees to staff its union positions with members trained and certified through that system, rather than setting its own bar for what counts as qualified.

How Much Training Does a Union Plumber Get?

Most homeowners underestimate how much training this actually is.

To get into the UA apprenticeship program through Local 562, an applicant needs a high school diploma or equivalent, has to pass a math exam, a drug test, and a physical, and needs a valid driver’s license. That’s the entry bar, before any training starts.

Once accepted, the apprenticeship runs five years. Each year requires up to 2,000 hours of on-the-job training under a journeyman, plus a minimum of 216 hours of classroom instruction. Across five years, that adds up to roughly 10,000 hours of supervised field work and over 1,000 hours of classroom instruction before anyone reaches journeyman status. After that, union plumbers can keep going through continuing education and a UA STAR certification, which also counts toward college credit.

This isn’t a new structure the union came up with recently. The United Association made a five-year apprenticeship a national requirement in 1921, and its 1936 apprenticeship plan was the first one of its kind approved by the federal government. The training a Local 562 apprentice goes through today traces back almost a century.

Aren’t All Union Plumbing Shops the Same?

Not necessarily. Several signatory contractors work in the St. Louis area under UA Local 562, and like most of them, Linek takes on plenty of commercial and new-construction work. What sets Linek apart is that residential service is also a real priority, not treated as secondary.

Over a century in the same neighborhoods means our plumbers are used to what shows up in older St. Louis homes: galvanized supply lines, cast iron stacks, clay sewer laterals, layouts that don’t match a new-construction manual. Being union is foundational. Knowing this area’s housing quirks, however, is something not everyone specializes in. We’ve been doing that for over a hundred years.

What Union Membership Means for Pay, and Why That Matters to You

Being a signatory contractor means Linek pays into wages, health insurance, and retirement for its plumbers, and pays them hourly instead of by commission. A tech also gets paid for drive time and doesn’t cover the cost of a comeback out of pocket. That’s a real cost for a company to carry, and it’s also why the structure changes what the plumber in your home is working toward.

Linek has built its reputation around sending plumbers, not salespeople, meaning the person at your door is assessing your plumbing, not working toward a sales quota. Hourly pay reinforces that instead of working against it: there’s no commission riding on what gets recommended. Union training points the same direction. A five-year apprenticeship produces someone who can diagnose a problem and explain it, a different skill than closing a sale. Linek’s own hiring standard reflects the same thing: new hires join Local 562 as a condition of employment, not an option, and the company holds itself to a standard that predates the union side of things too: “If it can’t be done safely, don’t do it.”

The first practical result of all this, day to day, is consistency. When every plumber on staff went through the same apprenticeship and carries the same journeyman credential, you’re not depending on which specific person happened to be available that day.

Does Missouri Require Plumbers to Be Licensed?

There’s one more reason the union credential carries particular weight for homeowners here, separate from the training and pay points above.

Missouri has no statewide plumbing board, no state licensing exam, and no state plumbing license of any kind. Individual cities and counties decide on their own whether a plumber needs a license at all, and what that license requires. Plenty of St. Louis-area municipalities issue their own local plumbing licenses, but a license valid in one isn’t automatically recognized in the next one over, and no state-level standard ties them together.

In a state that ran its own licensing exam, a state license would be the baseline proof that a plumber cleared some minimum bar. Missouri doesn’t have that baseline. A union credential fills part of that gap instead: a five-year apprenticeship, a journeyman test, and ongoing continuing education, run by an organization with no reason to grade its own members easily, add up to a real qualification standard in a state where the government isn’t setting one.

That’s not a knock on non-union plumbers, plenty of whom are skilled and careful. It’s one more reason the union credential carries practical weight in Missouri specifically, on top of the training and pay structure covered above.
