If your employer knows you are looking for a new job?

[HuntD]

Could there be any consequences if your employer knows you are looking for a new job?

As per my other threads I work for a awful organisation and I am actively looking for new work, although I haven't told anyone at work about my intentions I have updated my LinkedIn profile and the last sentence says "now looking to harness these, and other achievements in a challenging and rewarding environment".

Is this too obvious, and do you think it will lead to repercussions at work?
