Heads-up or Head-ups?

I am such an OC when it comes to spellings and pronunciations (though grammar is not something that I would consider myself an expert of). I sent an e-mail earlier to an office mate and used the word "heads up." She replied using the word "head ups." This got me thinking, which one is correct?

                   heads up vs. head ups

Apparently, none of the above is correct. There should be a dash (-) in between.

TheFreeDictionary defines this as:

          heads-up (hdzp)

          adj.

      Showing an alert, competent style: play heads-up basketball.

          n. Informal

      Information or notification, especially in advance: gave me the heads-up on the new security measures.

So, there...I was able to review on my spelling today. 

Clover Chips!

This is currently my favorite snack in the office... as in almost everyday snack. My boss reminded me I might have UTI because of eating too much of this. Hay, that's good reason enough to motivate me to stop munching on this!

Reminiscing

So much has happened since my last post. I am now on my 2nd year with the company, and so far, challenges in terms of understanding the business is being addressed gradually. My boss transferred me from the fixed line business to the wireless business. I appreciate that they have also promoted me to a higher job grade. Earlier in February, I had a hysterectomy operation so this is the 4th month that I've experienced no pain after more than 10 years of monthly agony due to myoma. God has been so good and I am excited to see what He has in store for me and my family for the rest of this year.
