Q: Resuming its normal "operation" or "operations"? Which one is correct when you write office close notice:

*

*The office will resume its normal operations on Monday, DD/MM/YY...

*The office will resume its normal operation on Monday, DD/MM/YY...

If both are right, which one is more commonly used?

A: I believe that both are correct. They are both understandable and unambiguous.
To me, "resume normal operations" implies that it will resume its normal tasks.
And "resume its normal operation" implies that it will operate in its normal manner.
These implications are both clear and mean the same thing.
