Warm wishes for a great co-worker.

Working with you is one of my favorite perks. You rank right up there with paid holidays and coffee breaks.

Happy birthday, now stop reading this card and get back to work.

If you were expecting a big bonus and a promotion for your birthday, you're going to be disapointed because all you're getting is a big cake and this card.

The only reason why I came into the office today was to wish you a happy birthday. It certainly wasn't for the money!

Nobody stretches a lunch hour like you.

I couldn't imagine working with anyone else. Happy birthday.

Wishing you a productive workday.

Wishing you a big bonus and a big raise this year.

Working with you just makes the day fly by. Happy birthday.

Congratulations, you are another year closer to retirement.

It's your birthday so sit back, relax, and don't do a thing; that should be really easy for you, just pretend you're at work.

You are really a delight to work with.

Keep working hard, but not too hard. Happy birthday.

Wishing you a care free birthday.
