Probation gets talked about as if it were a trapdoor you spend three months trying not to fall through, and that framing is exactly what makes people freeze. A typical UK probation runs three to six months, and yes, the notice period during it is usually shorter on both sides - often a week rather than the full contractual term - which is precisely why it feels precarious. But the company has just spent real money hiring you. They are not lying in wait for an excuse to let you go; they want you to work out, and your job is to give them every reason to confirm it early.
Get clear on what "good" looks like
In your first week, ask your manager a question most new starters never think to ask: "What does success in this role look like at the end of probation?" Pin down the specifics - the three or four things they will actually be judging. Without that, you are guessing at the target, and a surprising number of probation worries come down to nothing more than mismatched expectations that a single direct question would have cleared up.
Then turn that into early, visible goals. You will not transform the department in month one, and trying to is a classic way to irritate the people you most need on side. Pick something achievable and finish it. A small win that lands cleanly builds more trust than an ambitious project you leave half-done.
Ask for check-ins - do not wait to be reviewed
Request a short catch-up every couple of weeks rather than waiting for the formal probation review to tell you how it is going. Two reasons this matters:
- It surfaces small problems while they are still small, before they harden into "concerns" written down on a form.
- It signals that you are engaged and self-aware, which is half of what managers are quietly assessing anyway - the other half being whether the team actually enjoys working with you.
If feedback comes that stings, take it without flinching and act on it visibly. The new starter who hears "you need to ask more questions before diving in" and obviously changes the next week earns more goodwill than the one who got everything right but never adjusted to anything.
If it is genuinely not working
Sometimes the role is wrong, or the manager is, and no amount of effort fixes a bad fit. If your gut is telling you that early, raise it honestly in a check-in rather than soldiering on and hoping - a frank conversation occasionally reshapes the role into something that works. Know your rights too: even during probation you are protected by the Equality Act 2010 from discrimination, and ACAS can tell you exactly where you stand if something feels off.
