Recently my firm organized a holiday decorating contest as a friendly competition between teams. I am an employee, but my direct manager is offshore. A large majority of my work is spent with a team that asked me to be part of their team. A collection was taken, I contributed. When it came to brainstorming, I contributed some ideas that became the central theme. On the day I brought in home made bake goods. However when I saw the display it featured a photo of every team member (including non-employee contractors) but me. When they went out and got props they got them for all team members again but me.
I'll live, but I feel this is a kick in the teeth. Not only did I contribute to this effort (time, creativity and financial) I have been complimented on the work I have done for this team. What can I do? Note that the manager of this team contributes to my performance review
