I am not perfectly sure what call out means for such as this line.
The Atlanta Police Department said Wednesday that it was experiencing "a higher than usual number of call outs."
According to the Collins, I speculate the verb is used by the definition of the British English's
- (transitive) to order ( workers) to strike
So my questions are,
1 Am I correct in my speculation?
2 Even though Collins says it the British way of saying, doesn't it matter?
Thank you for your time
