This question is posted as first person but on the behalf of another person. Some details might be lacking.
I work in a nursing home, as a full time employee since two weeks. My contract is for a fixed term of 3 months that can be renewed in a regular indefinite duration contract. I am 50, working as nurse's auxiliary. My coworkers and my superiors are all younger than me by 10 to 30 years.
I noticed that they tend to go on break together without letting me know, that they sometimes interrupt speaking when I approach. What bothers me the most is that they also tend to have less consideration for handing me work they dislike: During task planning, I am sometimes assigned tasks nobody wants to do, and I often find that I have to finish work they didn't finish because they have spent their time socially bonding.
I do not get along well with most of them except a few, as they tend to get into morbid games such as guessing who's going to die next and in general our background cultures do not have much in common.
The times I tried to speak to them, for example at lunch, we talked about work to do, or what we did, and remained cordially distant. I remained silently listening for most of the time we were together as a group. I didn't manage to break the ice with them.
If not gaining their complete approval, I would like to know some effective ways to gain respect from an established group given that I have difficulties relating to them, at least to the point they consider me equal in terms of workload sharing and task assignment.
