I’m sorry you are struggling with this. He’s being an ass, and you owe him nothing. He is sexually harassing you and you should report him. Unfriend him on Facebook. He is being disrespectful to you and likely knows he makes you uncomfortable.

Report him to HR immediately. His behavior is unacceptable.
Make out reports for sexual harassment.
They need to put a stop to this.
Your workplace is toxic and hostile.
NO means NO.
Stop means STOP.
Don't remain quiet...you did nothing wrong.
STOP him. Speak up.

Be strong, firm, open, honest, and serious. It's tempting to try to get along, but if he doesn't respect your feelings, then not taking him on will make matters worse. Go to your supervisor, go to HR, go to your EEO Rep, and tell them now to protect yourself.

Tell him to cut the shit and that you aren't comfortable with it. If he countinues to do it he will find himself reported.

I’d say you need to be direct. “I hate it if you somehow got the wrong impression but I’m not interested “.
If he makes an asshole remark about not being interested in you, tell him that’s a relief. If his behavior continues after you have directly addressed it, that’s harassment and should be reported following your chain of command.

I’m really sorry. I know how uncomfortable this can be.

***I am sorry that you are being sexually harassed at work...I talked my girls who have been in similar situations, and Wee think this character is taking advantage of your sensitive, kind nature...He has no concept of Love & Romance(he is sexual preditore ), and perhaps you ought to use social defense; and straight him ought since he is clearly violating your social boundaries.....Look him in the eye and say " you are not type - now back off, or I will take action "...Women who are shy and sensitive are often prayed upon by sexual aggressors who see your nature as a weakness... He has history with his sick, behavior problem.... .......I noticed you write and think well, and I would Love to, perhaps, have on going discussion with you because you are interesting....Have an awesome day/night.....Bye for now, Ron...

There’s plenty of advice already posted. It sounds like you’ve already told him you’re not interested in anything more than a professional relationship. The next inappropriate contact must be reported to HR, although I understand that women’s complaints about harassment often are discounted and you have to be prepared for an inadequate response. . He’s putting you in an uncomfortable position. Protect yourself in anyway you must.Find allies at work. Keep his texts as evidence.

whatever happened to free love ?
Like free stuff, it's part of the new leftist tradition of sharing everything that ain't yours

Let this guy know emphatically that you do NOT seek relationships beyond professional interactions with married men. Especially at work. Inform him that all communication between you moving forward will be work related and professional or you will escalate the matter to your HR department.

Report him to hr. He is violating company policy. On a first offense (of this nature, anyway, I have fired first offenses that were more overtly sexual) they will usually council anonymously. Remind him of policy, explain that there "have been complaints" and put a record of it in his file.

His marriage is his business. Admittedly, that's pretty tasteless if he is cheating, but they may have an open marriage - so, don't judge too harshly.

In the final analysis, it's about what you want. Since our culture agrees that men have to be the ones to express interest, he is doing what everyone agrees he should do. If you aren't interested, then tell him. Say simply "I don't want to confuse you here; I'm not interested in dating you. You're a good guy, but I don't want to date you." It'll suck and his ego will take a hit, but he is the one that brought all that into work. If he can't be professional after he gets shot down, then he shouldn't have brought that into work.

If he doesn't take it well and it becomes a problem at work, then go to HR. He has to go.

Own the situation and this should go away fairly quickly. Silence is compliance, so you'll need to speak up and express what you want. Often that is adequate. If it isn't, then go to your employer. If the employer is any good, then it'll get dealt with quickly.

Tell him you are not interested. Make sure to include that his comments while flattering, are making you uncomfortable. Be honest with him. Tell him you would like to keep the work environment professional. If he cannot stop the compliments then I would consider unfriending him on Facebook. Keep all interaction with him work related and be up front when he tries to be flirtatious.

If you're not the charge nurse (or if he isn't) I would report it to her or him. Take a female witness with you from another dept or a friend who doesn't work there.

I'm the type of person who doesn't mix business with pleasure. I don't give guys an opportunity to hit on me at work.

My job is too important to compromise over one person.

Keep evidence on hand.
Tell him to back off in no uncertain terms. If you try anything more subtle than that if you do report him he'll claim mixed messages from you.
Then report him. I hate saying that, but you don't know what his reaction to rejection will be, what form the retaliation could take, including (but not limited too) sabotage at work. I know that it sucks to do something like report a guy, but I don't think you're going to have a choice. No one wants to be 'that' woman, but sometimes it is warranted.

You have to be firm with someone like that and politely inform them you are not interested in such discussions while on the job or even after your shift ends. If he persists in the advances, I would go to the human resources department (assuming your place of employment has one that is) and report him. I dealt with a similar circumstance with a female employee years ago that wouldn't let up and went to HR to report her for harassment. When situations like that come up, you can't be afraid to speak up, as it wouldn't be your fault any of that happened.

In my experience, this is a male, who allows his ‘sexual attraction free reign!’ If he puts ‘it’ out there and someone ‘bites,’ then it was all in the game! But, this is a dangerous game as people can get hurt or loose their job, it is not worth taking part in! I would state my position clearly and let him know that you are not interesting in playing games! Let this person know, that this is not fun, to you! If it continues, i would report it to your supervisor one time and if it continues, I would file a complaint.

By not "being clear with him" of YOUR intentions, he keeps following his. You haven't told him "no", you're "not interested". If you create tension in him, so be it. It's your sanity (and your image at work)... that's at stake. They all know about him...

You're asking the question, but you already know the answer. Trust your gut, Laura. Good luck, hon.

I would tell him to be respectful. And, if not, file a complaint.

Jeez.
Checking back when I find the post count has hit 100. And, it seems I'm the only one recommending a swift, and conclusive solution to this. Although @Kkgator comes pretty close. What the heck is wrong with you people? Be nice? Be "gentle"??? Someone should take this clod out to the parking lot and beat the tar out of him.

You can be nice, and straight forward at the same time. A simple "Please stop, you're making me uncomfortable," would be a good start. Any tension after that will be totally on him.

You have to tell him he's making you uncomfortable and to back off. Directly.

Can you talk to your HR/office manager? This is sexual harassment. I would had probably be on the samesituation, because Ibehave like you do. Then, I get to a point I become distant and cold with the person. If you don want to talk to HR or tell him to step back, then unfriend the guy from fb and avoid dealing with him for a while. He will get the hint.

That's tough. You should be yourself, no more no less. And tell him straight out, you have other interests, sorry pal, but that's how it is.
If he keeps it up......shift supervisor needs talked to.
Good luck.

Takes courage fist, get him have a coffee break and tell him like it is, platonic is as far as it goes and what he is doing may have to be addressed as harrassment.. You like him as a person but am not interested in establishing a relationship of non platonic nature.
