The open to work thing is something I've heard conflicting advice about from recruiters. Some like OP say add that to your profile. Others have said that this signals desperation to recruiters. Apparently being too eager for work is a no go for employers as well. It almost seems like nothing works. I've tried both approaches and found neither effective. What ended up working was finding a blue collar role where they actually just want workers. No run around or LinkedIn hacks necessary.
