This question is about a retail environment
We are a high-profile shop selling expensive premium items. Customer care is obviously a high priority.
The colleague in question was hired primarily for her skill in talking to customers in Chinese, as we have a lot of Chinese customers.
The problem is that the co-worker, after working four months, has not picked up on anything that is required for her job.
She does speak to Chinese customers and even initiates some deals.
When it comes to anything but speaking to customers, she is a net negative for the whole team. She refuses to do basic tasks that are expected of every worker in the company. She does so in a pleading manner, so that usually at least one colleague (usually me) steps in to do the job. Even if she is willing to do a task, she usually has questions about obvious problems (multiple times for the same problem). In that case she ties down at least one other co-worker for the time being. It is the consensus within our team, that said co-worker is a nice person but is draining more of the team's productivity than providing to it.
Management is insisting that they need her
We are sure there is some person out there that speaks Chinese and actually does their job in beneficial way.
I'd like to stress, that we are not actually intent on "getting rid" of the colleague. We are just disillusioned about helping her to not drain us.
Due to the nature of this environment, her performance is "distributed" on ours.
What can we, as employees do in this case?
