To Whom It May Concern: Letter of Recommendation
Dear Sir/Madam,
I am writing to recommend Tirim… to you. He has experience working for various companies in the past. He is my nephew, and knowing him so well I believe he will be of value to your establishment.
As an employee, Tirim… was always punctual, obedient, honest and hard-working. Those who worked with him have often reported how positive his disposition is to any task given to him.
I’ve always put a premium on his reliability as he never fails to deliver. For example, he has worked with chemche… Foods for more than a decade.
Tirim…. is a delight to work with and I wouldn’t hesitate to recommend him to your company.
Warm Regards,
Baale…
