I worked from home in the month of December for two weeks with my manager's permission. My manager also allowed me to work from home for the next two weeks. A month after this happened a colleague told me that my teammates were talking about my absence and worried if I have some personal problem or if I don't like the job. My colleague also mentioned that, 'Too many days working from home might rise up as a question or concern during the annual review'.
My manager gave me permission to work from home, but I don't want it to reflect poorly on me.
How do I best determine if company policy and generally acceptable practice do not align?
