The insects were brought to our office in a bag with an oatmeal box. The lid was at least half way covered with these tiny insects. She said they seem to be located in a cupboard around flour and cereal.

yes, certainly a Tribolium
-
Moved from Beetles.

Really looks like
a common mealworm beetle, one of the Tenebrio species.

 
Dark Image
The image is dark, but I would lean towards one of the Tribolium species.

Compare (not an ID):

 
Tenebrio is nearly “flightless”
Adults (contrary to many claims) have functioning wings, but rarely ever fly. It is also unlikely to colonize bagged cereal for this and other reasons.

“Tiny” is a vague word, but it does point to Tribolium as a more likely culprit
