A recruiter tells you the role is a six-month contract "with a view to permanent". Your first instinct is to file it below a real job, somewhere between a stopgap and a rejection. That instinct is half right. Contract-to-hire is the most reliable side door into employers who have work piling up but no open permanent headcount, and it is also the arrangement in which candidates most often spend nine useful months working for someone who was never going to hire them. Both halves are true. Which one you end up in is mostly decided in the twenty minutes before you sign, not by how well you work afterwards.
The three shapes the arrangement takes
People say "contract to hire" as if it names one thing. It names three, and they have wildly different odds.
A defined trial with a stated conversion date. The contract says six months, names a review point, and either sets out the permanent terms or commits the employer to presenting them by a date. The hiring manager already has approved headcount and is using the contract as a probation period with a shorter exit. This is the good version. Conversion rates here are high because the permanent job already exists on a spreadsheet somewhere.
An open-ended contract where conversion is "possible". No date, no approved role, a manager who genuinely means it when they say they would love to keep you. Conversion depends on a budget cycle you cannot see. Sometimes it lands. Often the contract just rolls on in three-month extensions for two years.
A temp assignment with no conversion path, advertised as though it has one. Someone is on parental leave, a system migration needs bodies until March, a backlog needs clearing. The word "permanent" appears in the advert because it doubles the applicant pool at no cost. Nobody involved is lying exactly. Nobody has approved anything either.
Your entire job at offer stage is working out which of the three you are being handed.
Why the employer picked this route
The reason matters more than the job description, because it sets your actual odds.
Budget sitting in the wrong line. Contractor spend often comes out of a project or operating budget, while permanent salaries come out of headcount, which is controlled centrally and frozen more easily. A manager with 80k of project budget and zero headcount can hire you tomorrow as a contractor and cannot hire you at all as an employee. Conversion then depends on headcount reopening, which is a decision made three levels above your manager.
A hiring freeze with real work still to do. Same mechanism, more explicit. Freezes usually have an end date attached to a quarter. Ask when the freeze started, because a freeze in month fourteen is not a freeze, it is a policy.
Risk aversion after a bad hire. The team hired someone who did not work out, spent five months managing them out, and the manager now wants a trial before committing. Your odds here are the best of the three, because the money exists and the only question is you.
There is a fourth reason worth naming: some employers use contract-to-hire as a permanent staffing model and never convert anyone. You detect this with one question, below.
The questions to ask before you accept
This is the part that earns the article. Ask these on a call, not by email, and listen for hesitation as much as content.
- Is the conversion date written into the contract? Not "we usually convert around six months". Written, with a date. If it is not written, treat the conversion as marketing.
- Has anyone in this specific team converted, and when? Team, not company. A company with a 60 percent conversion rate can contain a team that has converted nobody since 2023. If the answer is vague, ask for a name and role you could look up.
- Who signs off on the conversion? You want a named person and their level. If the manager says "it goes to finance and then group", you have learned that your manager cannot deliver what they are offering.
- What happens if you want me but headcount does not open? The honest answer is "we extend the contract and keep pushing". Anyone who says this is not a risk is either uninformed or handling you.
- Is there a conversion fee owed to the agency, and has it been budgeted? Ask the employer and the agency separately, then compare the answers.
- What is the trigger that makes this conversation happen? A date, a project milestone, the next budget round. If nobody can name the trigger, there is no process, only goodwill.
Two of these answers being weak is a yellow flag. Four being weak means you are in shape number three and should price the role accordingly.
The agency fee nobody mentions
If you are placed through a staffing firm, the employer typically owes that firm a conversion fee when they take you on permanently, often a percentage of your first-year salary, sometimes tapering the longer you have been on contract. On a 55k salary a 20 percent fee is 11k that has to come from somewhere.
This is a common silent killer. The manager wants you, the work justifies the role, and then a finance business partner points out that converting you costs an extra 11k this quarter that nobody planned for. The conversation does not get refused, it gets postponed, then postponed again, and eventually you are an eighteen-month contractor.
Two practical moves. Ask whether the fee tapers to zero after a set number of months, because if it drops to nothing at twelve months, the employer has a strong reason to wait and you should know that rather than reading the delay as rejection. And ask the agency whether the client has already agreed the fee in writing, because a contract with pre-agreed conversion terms is a completely different risk profile from one where it will be negotiated under pressure later.
What to do during the contract
Working hard is necessary and does nothing on its own. Contractors who convert tend to have done three specific things.
Owned something visible with their name on it. Not tasks, a thing. The reporting pipeline, the onboarding flow, the vendor relationship. When a manager argues for headcount, they need a sentence that starts "if we lose this person we lose". Overflow work does not produce that sentence. If six weeks in you are only absorbing whatever nobody else has time for, ask your manager for one area to own outright, and say plainly that you are asking because you want to convert.
Built a relationship with whoever signs off. You identified that person before you accepted. They should know your name and what you do from something other than your manager's advocacy. A fifteen-minute conversation about their problems in month two is worth more than another month of output.
Kept a record. Contractors almost never get a formal review, so nobody is accumulating evidence for you. Keep a running note of what shipped, what it saved or unblocked, and quotes from people who benefited. When the budget conversation happens, your manager needs material, and they will use whatever you hand them.
When to walk
The tells are consistent. Your conversion date passes and gets replaced by another vague one. You are excluded from planning for the period after your contract ends. A permanent role that looks like yours gets advertised externally. Your manager stops giving a direct answer and starts saying "I'm pushing for it". A second contractor arrives on the same terms.
One rule covers all of it: keep searching until a signed permanent offer is in your hand. Not a verbal yes, not an email saying it is going to HR. People stop applying the week a manager says "we are working on your conversion" and then lose four months. Run the contract and the search in parallel, and if an external permanent offer arrives, tell your manager. A real conversion process accelerates. A fictional one produces sympathy.
The practical differences while you are on contract
Contractors usually get no company pension contribution, no private healthcare, no sick pay beyond statutory, and no bonus. Notice is often one or two weeks in both directions, sometimes less. Holiday may be unpaid or rolled into your rate, which means your day rate is not comparable to a salary until you subtract the days you will not be paid for. A rate that looks 20 percent above the permanent salary frequently is not, once pension, paid leave and sick cover are priced in. Do that arithmetic before you compare offers, not after.
Who this is right for
Career changers get the most out of it, because a contract lets an employer try someone whose background does not match on paper, which is exactly the decision they will not make for a permanent hire. It works similarly well for people re-entering after a break, and for anyone relocating into a market where their previous employers mean nothing to local hiring managers.
It is wrong for you if you need visa sponsorship tied to permanent employment, if you have no financial cushion for a gap after the contract, or if you already have permanent interviews in play. In that last case, the contract mostly buys you an excuse to stop searching, which is the one thing you cannot afford.
