Dear Sir,

I have decided to write to you so you have a clear record of my concerns. My grievance relates to a fellow employee with whom it has become increasingly difficult to work alongside.

Mark Jones from the Sales Department has repeatedly ignored my requests for further information about clients he is speaking to, and is unwilling to share information necessary for me to complete my job. This is subsequently giving the appearance that I am not completing tasks, which is not the case and a situation that is causing me some considerable distress.

I would respectfully suggest that Mr Jones be informed of company policy regarding client information and be strongly encouraged to be more open and forthright with colleagues so that we can all achieve our goals. It seems that Mr Jones is not particularly focused on teamwork, and this is causing some resentment around the office.

Hoping for your swift action in this matter,

John Player, Human Resources Department
