I would say, "look here. Do you have a problem with me coming in at 745? Does my coming in at 745 affect your work at all? Because my boss has no problem with me coming in at 0745?"

I would say "yep, you get great hours when you're a bada*s" and walk the hell off.

oh, I dislike that attitude.
I personally could care less what my co-workers are doing most of time.
It's up to management to deal with it; one co-worker was pushing the limits and her work was being passed onto other people a little too often, and then she was shut down.

AND if you are a salaried employee, there's especially no reason to comment on hours! That drives me nutso. I agree with advice.only. If he's addressing you directly enough then I'd refer him to your manager and let him know you don't want to hear it.

When he addresses you in this manner confront him directly. Tell him that your work schedule is between you and your supervisor and is none of his business. Then inform him that if he continues to harras you that you will speak to both your supervisor and his supervisor about it and if necessary make a formal complaint to HR.

I have found that directly addressing this type of thing is never as difficult as we tend to build it up in our own minds to be.

Never have I or my wife had to take an issue to HR once the perpetrator has been addressed directly in front of the supervisors.

When these weasles are instructed to attend a meeting between themselves, the complaintant, and the respective supervisors, following the meeting they tend to wilt and knock of their crap.

Good luck.

This man is NOT your boss. I agree with telling him that your work schedule is between you and your supervisor. Period. Dot.

I once had an issue with a team lead who insisted I give him weekly updates on my progress. Since I very rarely did any work for this person (maybe 1-2 times a year), my progress email read, "not currently working on this project". This jackwad sent me a nasty email DEMANDING I tell him exactly what I was working on. So I went to our boss and said, "Boss, do I report directly to you or to Jackwad?" The boss looked at me curiously and said, "Me. ALWAYS. Jackwad is a teammate. You never report to him." I explained to the boss about Jackwad's emails, so the boss called Jackwad into his office and said, "Allow me to clarify. You are NOT Aniki's boss. Aniki does NOT report to you. Aniki reports to ME. IF Aniki does any work on your part of the project, she will give you a status ONLY FOR THAT WORK. Until that time, get off her back. She's busy with critical projects for ME." Jackwad didn't last much longer.

I'd be irritated as well, but unfortunately, jerks will be jerks.

My approach would be to stare at the middle of his forehead until he stops talking. Then walk away/turn back to your work/go back to getting your coffee.

You can decide if this is an actual conversation or just one guy talking to air.

I would suspect this guy is of the opinion that mothers shouldn't work. And also feels you are being given special treatment because you are a mother.

You should just ignore him. However, if you find you can no longer let this go, a simple "yup, I'm a bad ass mommy. You wouldn't understand" and walk away

He's not your boss, you do not report to him..... ignore the old fart lol....

next time he makes a comment about oh look who showed up, smile and say... yes some of us have a life outside the office and hot husbands then wink.... (you meant nothing by this but he's going to take it so differently lol he might blush)

I would not go to HR about it, might look like you are a nag, but then I'm very quick with my replies and I do not care about how the other person feels, I'm sorry but if you behave like a toffee you should be prepared to be chewed...
I deal with my own things, I do not need HR lol.... and I always keep it friendly and just above insulting a person

We have an open office, you can go and complain about me, the other office people will say - no Acra was very chirpy and friendly, LuLu is just having issues - see now HR thinks you are the problem

You where raised to respect older people, Hon they have to respect you as well and if they don't... the game is on, you do not have to be rude to tell them off, you just have to be witty and clever, he should only figure out hours later you actually told him to eff off...

Like many issues, the devil is in the details. My biggest question is what are the weekly work hours required and what are the company's policies regarding attendance?

I will probably get jumped on here for looking at this a bit differently.

If the company's policy and REQUIREMENT that employees must work a minimum of X hours per week which can be accomplished with flexibility (as long as work is done) and you are fulfilling those requirements, then it's pretty clear cut.

However, in my own work place, there are people who need flexible time for personal reasons but other people wind up picking up work load to accommodate their schedules. Someone has to be here during "core" business hours, so having some people being excused from that schedule creates problems and strife. Everyone has family, health, personal issues, etc. but we have a select group of employees whose "flexible" hours are accommodated, and others must pick up the slack.

Here - the jobs are the same but some employees are allowed to flex their schedules, but others must take vacation/sick time if they cannot be here during specified hours. It's totally unbalanced. Especially when some individuals have to burn up their vacation time when they are not here during those hours, while others don't.

If OP's company has the same kind of "policy" then I might be able to understand why the other employee is making sideline comments - not saying he is right to do so, and he needs to knock it off - but it needs to be understood in context.

It certainly may not be the case here, all I'm saying that there can be another side to this issue ...flexing work hours for some people but not others does create issues.

Oh and one more point, assuming the OP is here in the US, I would be cautious about referring to the other employee as the "old" guy and making statements about his age: "Like should be retired ... " If this attitude is seeping into her attitude and/or comments to this man, she may find herself in HR. Age discrimination is against the law.

When he spouts off one of his nasty little quips respond with:

"Why would you say that to me?" or "Why would you ask a question like that?" "What did you mean by that?"

Respond with a question every time he says something and it will likely stop since he only wants to bully and not be confronted.
