"xxxx and I would like to take this opportunity to thank you for the time and effort you have contributed to making our new company work since August 2013. We are really grateful for your continued dedication.
To demonstrate our appreciation, we have added a Christmas Bonus to your December 2013 salary.
We understand that you have only worked with us for 5 months in 2013 but we would like to draw to your attention that this bonus is discretionary and that it has not been calculated on a pro-rata basis.
May I remind you that your salary is confidential and should not be discussed with other members of staff.
