My coworker and I are competing for the upcoming promotion. When I luckily got the said promotion, he began to hate me more. I donít know if heís gay for hating me like this or he just badly needs the promotion. I had a foreign client one time who happened to cancel his order because this co-worker of mine told him so and asked the client to transfer to him. I donít know what story he has put up to convince the client. Heís getting into my nerves. I sometimes feel like I want to take revenge but I decided not to. I donít know what to do with these kind of people anymore.
