New Lead, Veteran Journeyman, and a Skipped Slab Check
Marcus was promoted to crew lead three weeks ago and now supervises a six-person concrete crew, including Ray, a 19-year journeyman who has been on the site since mobilization. The project is a 14,000-square-foot warehouse slab with a pour scheduled Thursday at 6 a.m. Tuesday afternoon Marcus sees Ray telling two finishers to skip the final elevation check on grid lines C through F because 'the laser was checked Monday and nothing moved.' The pour requires a 3/8-inch tolerance. Marcus has not yet reviewed the laser setup himself. Ray's instructions conflict with the checklist the general contractor requires initialed before each placement. The two finishers are waiting and the crew is already 40 minutes behind because a pump truck arrived late. Ray tells Marcus in front of the crew that he has poured more slabs than Marcus has seen.
1. What should Marcus do right now, before the finishers act on Ray's instruction? Explain the reasoning behind the order of actions.

First, secure the work. Marcus should tell the two finishers to hold while he personally verifies the laser against a known benchmark and checks the required 3/8-inch tolerance on lines C–F. He should then initial the GC checklist himself or have the designated checker do it.
Why not simply overrule Ray publicly? Publicly reversing Ray may settle the immediate point but turns the correction into a status contest in front of the crew. The urgent risk is a nonconforming slab, not Ray's comment. A calm 'hold for five minutes' keeps the decision technical and leaves the conduct issue for a private conversation.
Why verify rather than accept Ray's assurance? The laser was checked Monday, but the checklist is required before each placement, and Marcus has not confirmed the setup. If the elevation is off, the cost is far greater than a short delay. Once the check passes, Marcus can release the pour and address the bypass separately. He should also note the pump-truck delay in the daily log because schedule pressure is driving the shortcut.
2. After the pour is secured, how should Marcus address Ray's behavior privately, and what should be documented?

Marcus should speak with Ray privately, soon after the pour, and describe the specific behavior rather than the person: Ray directed finishers to skip a required check and challenged Marcus's authority in front of the crew. He should ask Ray for his view, because a 19-year journeyman may have information about the laser or the schedule that Marcus lacks, and listening costs nothing.
Then Marcus should state the standard clearly: checks are required before each placement, and disagreements are raised with Marcus directly, not by directing the crew to bypass a check. He should ask for Ray's commitment and offer to use Ray's experience in planning the next pour.
Documentation: a dated coaching note in the supervisor's log-what was observed, what was discussed, and Ray's response-not a formal reprimand unless policy requires it. The note protects the crew if the behavior recurs and shows a pattern. Marcus should not promise confidentiality he cannot keep, but he should not broadcast the conversation either.
3. Ray repeats the behavior two days later and tells the crew that Marcus 'doesn't know slab work.' What should Marcus do next?

Two days later the conduct is no longer a single lapse; it is a pattern that undermines the checklists and Marcus's ability to lead. Marcus should again address it directly, but this time with a written expectation and a clear consequence, and he should notify his superintendent or project manager rather than handle it alone. A crew lead who conceals repeat insubordination is exposed if a quality or safety failure follows.
He should document the second incident factually-date, time, what Ray said, who heard it, and what Marcus directed-and ask his supervisor for support, whether coaching, reassignment, or formal discipline under company policy. Reassignment should be considered if Ray's influence is splitting the crew, but it should be presented as a work decision, not a public humiliation. Marcus should also keep the two finishers focused on the standard so the conflict does not become a loyalty test. The goal is a crew that follows required checks, not a personal win over Ray.
