I think I will just try and ignore them and not offer them help when they need anymore, it's just annoying that when I come to work there is that happening, I mean it's not like are kids.....

So well I don't know if there's a fix for the situation, but so I guess it would already help to have someone to talk with about this.

Just something about me: I am a introvert person, during my bachelor I did my internships at a company and it was kinda like you come in do your work if help is needed you just ask and go on etc.
I started my PhD almost 2 years ago and am always busy helping others setup their experiments, do mine own experiments some side projects etc. I know I am doing atleast alright in terms of research since I will probably get my first publication soon along with atleast 1 more this year, other then that I am always busy with work from the moment I come in at 8:30AM till I leave sometimes till midnight.

Now about a year ago some new people joined the group and they together with a staff member are very very chatty to the point that they are just gossiping about groupmembers, on facebook for more then just a moment during work, etc. To the point that they are saying stuff to the Professor that are simply not true. so far I have been trying to avoid them a bit during lunch because they act like that and I find it quite dumb to be gossiping about colleagues so is there something I can do or should I just stick it out for 2 more years? I already mentioned to the professor once that certain stuff they didn't tell the whole story, like they saying I didn't want to help organize something while they never included me in the discussions from the beginning nor asked me to be involved, just did it among themselves.
