(名詞/可數) 幽靈同事 － 同一家公司的同事，但通常在家裡獨自作業且不常與其他同事接觸或聯絡的人。
Two years of remote working have taken their toll on work relationships and company culture, giving rise to 'ghost colleagues'. These are employees who, because they don't directly work with many others, end up being 'forgotten'. They tend to feel isolated from others and from the overall direction of the company.
