Quick Summary: As a subcontractor, you are responsible for your crew’s conduct on a GC-managed site, and your Master Service Agreement (MSA) almost certainly spells that out in writing. A single behavioural incident can trigger removal from a jobsite, damage your position on a vendor list, or expose you to indemnification claims. Getting your internal conduct policy right before your phone rings is cheaper than managing the fallout after.
Field crew conduct is one of the least-discussed business risks in the subcontracting world. Safety compliance, Field Ticket accuracy, and billing disputes get most of the attention. But a foreman who gets into a shouting match with a GC superintendent, a crew member who harasses a co-worker on a multi-employer site, or a technician who shows up to a wellsite impaired can end your relationship with a GC faster than a missed deadline ever could. This guide covers what you are actually liable for, how to respond when the call comes, and what a practical internal conduct policy looks like before any of this happens to you.
What Subcontractors Are Actually Liable for When Crew Conduct Creates Problems
Your crew is your responsibility. That is the starting point, and your contracts reinforce it.
Most GC agreements and Master Service Agreements (MSAs) include language requiring the subcontractor to control, supervise, and be responsible for the acts of their employees and sub-tier contractors while on site. When your crew creates a conflict, damages equipment, harasses another worker, or violates a site policy, that liability typically flows back to you under three mechanisms:
Respondeat Superior. Under this common law doctrine, employers are liable for the wrongful acts of their employees when those acts occur within the scope of employment. If your ironworker assaults another worker during a shift dispute, you likely share exposure for that incident. The fact that you were not on site is irrelevant.
Contractual Indemnification. Most MSAs contain an indemnification clause requiring the subcontractor to defend and hold harmless the GC against claims arising from the subcontractor’s work or personnel. Read your indemnification clause carefully. Broad “arising out of or related to” language can pull in conduct incidents that you would not expect to be your problem.
Multi-Employer Worksite Liability. On a construction site with multiple employers, OSHA’s multi-employer citation policy allows citations to be issued to creating, exposing, or controlling employers, not just the employer of the injured or affected worker. Supervisors and foremen who create hazardous conditions can expose your company even when the affected worker belongs to another trade.
A practical example: A pipeline subcontractor’s foreman in the Permian Basin gets into a physical confrontation with a GC safety inspector over a toolbox talk dispute. The GC fires the foreman from the site immediately. The incident report goes to their HSE department, gets attached to the subcontractor’s vendor file, and triggers a review of the MSA. The subcontractor is placed on a 90-day probation, required to provide a corrective action plan, and loses priority consideration for the next bid cycle. None of that required the GC to prove negligence in court.
How GC Contracts and MSAs Allocate Responsibility for Field Personnel Conduct
Before the next project kicks off, pull your MSA and read these sections with fresh eyes.
| MSA Section | What to Look For |
|---|---|
| Personnel/Supervision Clause | Does it require your crew to comply with GC site rules? Who has authority to remove personnel from site? |
| Indemnification Clause | How broad is “arising out of”? Does it include your employees’ independent acts? |
| Termination for Cause | What conduct triggers immediate termination rights for the GC? Is written notice required? |
| Termination for Convenience | Can the GC end the subcontract without cause? What compensation do you receive? |
| Code of Conduct / Site Rules | Are you bound by the GC’s code by reference? Do you have a copy? |
| Insurance Requirements | Does your GL policy cover conduct-related claims, or only property and injury? |
The personnel clause is where most of your exposure lives. Many MSAs give the GC unilateral authority to remove any subcontractor employee from the site at any time, for any reason, without that constituting a breach of contract. They do not need to prove anything. They just need to ask.
Termination for Convenience clauses compound this risk. Even if your crew’s conduct does not rise to a “for cause” event, the GC can exit the relationship without owing you a full contract value. If a pattern of conduct incidents erodes the GC’s confidence in your company, convenience termination is the path of least resistance for them.
Review your MSA with your attorney specifically for conduct-related language before you start work. If you have a Price Book relationship or blanket order with a major operator or GC, the same review applies.
How to Respond When the GC Calls About Your Crew
The phone rings. The GC superintendent or HSE manager tells you there was an incident with one of your people. Here is how you handle it.
Step 1: Listen first, defend nothing. Your immediate job is to collect information. Get the name of the employee, the date, time, location, a description of what occurred, and who witnessed it. Do not defend your crew member on the call. You were not there.
Step 2: Acknowledge and commit to follow-up. Tell the GC you take it seriously, that you will investigate, and that you will come back to them within a defined timeframe (24 hours for a serious incident, same business day if someone was removed from site). Give them a specific name and number to reach.
Step 3: Talk to your foreman or crew member directly. Get their account in writing. Separate them from any co-workers who might influence the narrative. If there is a written incident report from the GC, request a copy before the conversation.
Step 4: Do not stall on visible action. If the GC removed someone from site pending investigation, do not put them back until you have a corrective action plan the GC has accepted. Pushing back on a site removal before you understand the facts is one of the fastest ways to escalate a single incident into a contract review.
Step 5: Respond in writing. After your investigation, send the GC a written response. It should include: a factual summary of what you found, any corrective actions taken (written warning, retraining, reassignment, or termination), and the steps you are taking to prevent recurrence. Keep this professional and factual. The written response becomes part of your vendor file.
Step 6: Loop in your insurance broker or legal counsel. If the incident involves physical altercation, harassment, impairment, or injury, do not wait to see how things develop. Make the call now.
Can a Single Incident Get You Removed from an MSA or Vendor List?
Yes. And it happens more often than subcontractors expect.
A single serious incident, specifically one involving violence, harassment, impairment, or a safety violation that draws regulatory attention, can trigger an immediate review of your MSA standing or vendor qualification status. On platforms like ISNetworld or Browz, GCs and operators track safety and compliance incidents. A substantiated conduct complaint can show up in your profile and affect your prequalification scores for bids beyond the immediate GC relationship.
The threshold for removal varies by company and contract, but here is what typically triggers the most serious responses:
- Physical altercation between your crew and GC staff or other trades
- Sexual harassment or discrimination complaints
- On-site impairment or positive drug test
- Verbal threats or intimidation directed at GC personnel
- Repeated minor incidents that form a documented pattern
- A conduct incident that generates a regulatory complaint or media attention
A single poorly handled foreman outburst rarely ends a multi-year MSA if you respond well and fast. Where relationships break down is when the subcontractor minimizes the incident, delays action, or makes the GC fight to get a straight answer. The cover-up tends to be worse than the crime.
What a Practical Internal Conduct Policy Should Include
Your internal conduct policy needs to do two things: set clear expectations for your crew before something happens, and give you a documented framework to act on if it does. Here is a baseline checklist.
Essential Elements of a Field Conduct Policy
- Written code of conduct covering harassment, discrimination, violence, impairment, and site rule compliance
- Clear definition of what constitutes a terminable offence versus a correctable one
- Acknowledgment form signed by every employee at hire and annually
- Foreman authority and responsibility explicitly defined (foremen are accountable for their crew’s conduct, not just their work quality)
- Site Orientation protocol that includes review of both your company rules and the GC’s site-specific rules before work begins
- Incident reporting procedure: who your crew reports to, in what timeframe, and in what format
- Disciplinary ladder: verbal warning, written warning, suspension, termination, with documentation requirements at each step
- Zero-tolerance items listed explicitly (violence, impairment, sexual harassment, threatening GC personnel)
- A process for investigating complaints that protects both the complainant and the accused before action is taken
- A statement that GC site removal does not automatically constitute wrongful termination but triggers an internal investigation
That last point matters more than most subcontractors realize. If a GC removes your foreman from a site and you terminate him the same day without investigation, you may be exposed to a wrongful dismissal claim. A documented investigation, even a brief one, gives you the procedural foundation to support the termination if it comes to that.
Disciplinary Steps That Protect You on Both Sides
You are managing two sets of risk simultaneously: the GC’s concern about your crew, and your crew member’s employment rights. The disciplinary process needs to address both.
The basic principle is documentation at every step. A verbal warning that is not written down did not happen in any employment claim that follows. When you issue a written warning, it should include the specific conduct, the date, what was observed or reported, the expected change in behaviour, and the consequence if it recurs. Get a signature. If the employee refuses to sign, note that in writing too.
For serious incidents, a paid investigative suspension while you gather facts is better than either immediate termination or doing nothing. It signals to the GC that you are acting, while giving you time to build a defensible record. If the investigation supports termination, proceed with termination. If it supports lesser action, document why and what remediation you are requiring.
Keep all conduct-related documentation separate from payroll records and accessible only to owners or HR. If the matter ever reaches an employment tribunal or a contract dispute, you want a clean, complete file, not a pile of texts and handwritten notes.
Bottom Line
Your crew’s behaviour on a GC-managed site is your business problem, full stop. The contracts say so, the law generally supports it, and GCs have the practical authority to act before any of it goes to court. Build your internal conduct policy before you need it, respond to GC complaints with speed and transparency, and document every disciplinary step as if a judge will read it later. The subcontractors who stay on vendor lists through difficult incidents are not the ones whose crews never cause problems. They are the ones who handle problems professionally when they do.
