Hello Everyone,

I have found a mistake, look at below: "One can learn a lot about an employee or coworker by spending time with the person on his or her off-time."
In my view, it should be "time off" instead of "off-time"
According to definition, "time off - a time period when you are not required to work"
For more information, go to this link:

http://www.thefreedictionary.com/time+off

Off-time, " In resistance welding, usually in repetitive cycles, the time that the electrode is not in contact with the work"

Kind regards,

Though it may not appear in the dictionary. 'off-time' is in fact a reasonably common casual equivalent of 'time off'. In any case, however, test errors are not being corrected for the moment.
