The pandemic has had an impact on our resources, because ………. :

“More than half the team have been absent from work.”

• This sentence is clear, direct, and grammatically correct. It precisely communicates the extent of the absenteeism due to the pandemic.

“It has been over half of the team absent from work.”

• This sentence is somewhat awkward and not grammatically correct. The phrasing “It has been over half of the team” is unclear and should be restructured for better clarity.

“It is understood that half of the team are absent from work.”

• This sentence is grammatically correct but uses passive voice, making it less direct. Additionally, “It is understood” is somewhat vague and can imply hearsay or lack of direct knowledge.

Overall, the first option is preferred because it communicates the information clearly and directly.
