Can my employer know I am looking for another job?

Usually not, unless you tell them one of the five ways people do.

Nobody at your company gets an alert when you start looking. What they get is evidence, and almost all of it comes from the same five places. Monitoring is rarer than people fear and leaks are more common than people think: the risk is not surveillance, it is habit.

The five ways they find out

• Your public profile changes. An open-to-work badge, a sudden run of new recruiter connections, a freshly polished headline. Recruiters at your own company use the same tools and see the same signals.
• Your work devices and accounts. Email, browser history and chat on a company laptop or network can be reviewed, and most policies say so. Treat anything on them as readable.
• A reference check. The most direct route of all: a prospective employer calls your current manager because nobody said they could not.
• A colleague. One confidence becomes two. The person who passes it on usually meant no harm.
• A job board or a resume database. A resume carrying your name and your employer is searchable by the people who hire for your employer, too.

What they cannot see

They cannot see applications made from a personal device on a personal network. They cannot see conversations on a platform that never publishes your name. They cannot see a profile that carries your skills but not your identity.

That last one is the gap IncognitoH is built into. You are findable for what you can do and anonymous until you decide otherwise: a recruiter at your own company sees the same anonymous card as anyone else, and an approach names the company before you answer, so one you would rather not have can be declined without a word about you.

Is looking allowed at all?

In most places, yes. Looking for a job breaches nothing unless your contract says so, and few do. What contracts and policies do cover is using company time, equipment or confidential information to do it, and the notice and non-compete terms that apply after you accept. Read yours before the first interview, not after the offer.

This is general information rather than legal advice; employment law differs by country and by state.

If you want to be certain

• Personal email, personal device, a network your employer does not run.
• No public signal until you have signed. An offer is not a job.
• Say who may be contacted as a reference, and that your current employer is not on the list yet.
• Be found rather than seen: a profile with no name on it cannot be reported to anyone.

The quiet way to look is to be found.
