Does work really affect a man's attitude at home?

I suggest you give the guy a break after work (at least an hour) so that he can have a chance to leave his work at work and unwind a bit so that he can become "nicer" around you and your baby. I'm always stressed out after I get back home but after watching the news or simply laying down for a few minutes gives me the chance to gain strength so that I can finish off the day with the presence of family.

Tension at work place can act as a catalyst to a man's attitude. And this tension necessarily wouldn't mean as coming from the extreme work load he might have. One of the major reasons happens to be competition within work place. But whatever the case, coming back home is always the best stress buster if he doesn't expect the same kind of nagging back home.

Very much so! See unlike women. A mans job is the most important thing to him besides his family. See in a relationship a woman will have a tendency to lose herself identity because she is so focused on him and making him happy. Men don't think like women at all. He will be so focused on work. He'll forget to call. He'll act distant. Etc. Now the ladies however. You know him better than I do. You know if he's a flirt or if he's more of a shy guy. Trust sweetheart. You must have trust. If he comes home and acts distant. Give him his space. Show your concerned, but don't force him to talk. He will come around to his normal self. Remember men see their home a stress free environment. Don't create stress by making him talk or arguing. He may not wanna come home then.

Career stresses definitely carry over into home life - it can't be avoided. After all, it's what we spend an enormous chunk of our lives doing. Unfortunately, the more seriously he takes his work, the more difficult it will be for him to let go of any stress caused by it when he comes home at night.

A few notes. About the women at work. You're obviously a serious couple if you're living together and have a baby together - the trust needs to be there. And if he feels like you don't trust him, he's going to be hurt and resentful. And even more stressed. Doesn't benefit anyone. My husband works with some really attractive women who also happen to be in our age bracket, which secretly made me a bit squirmy at first. But a couple of them actually ended up being great friends to have. They flirt with him from time to time, but no more than some of our friends flirt with me. So it doesn't bother me anymore - I know he's perfectly capable of handling himself and I trust him implicitly. He chose to be with you for a reason.

Anyway back to the main point. We all need to unwind after a stressful day at work. If we think that coming home is going to be stressful too, that just compounds things. So whatever his thing is, you need to let (and encourage) him to do it. If he works relatively nearby, commuting by bike has always been a huge benefit. It clears your mind, refreshes your body and helps transition you out of work mode, and into life mode. It works.

If he comes home and snaps at you, just walk away and leave him alone. Then AFTER he's cooled off you need to calmly and matter-of-fact make sure he knows that you understand he's under a lot of stress, but you won't be the dog he kicks at the end of the day. Don't get upset - just hand it to him straight. Tell him you'll give him some time to unwind after work if that's what he needs, but you deserve to be treated with some consideration.

It might be a good idea to make a habit of taking the baby out for a walk after work - along with him if he'd like to unwind with you, or by yourself if he'd rather unwind alone. Everybody wins.

Of course the work tension affects how he feels outside the work area. It isn't only for a "man" , if I had a crazy tense atmosphere and loads of stress at work. I'd be pissed half the time too. But I agree with Aditya. About the nagging at home. If he's given a break from any farther stress at home. He'd just might cheer up and not be so angry/cranky.
