Is it permissible to shorten the prayer (qasr) at the workplace if the distance exceeds the distance for shortening, whether during academic days or when returning to it for only two days to sign after the academic year has ended?

If the questioner does not intend permanent residence in her place of work, then her original homeland is her family's country, and prayer is performed in full there and is not shortened. When she goes to her city of work, she shortens the prayer unless she intends to stay for more than four days. However, if she intends permanent residence in her city of work, then she may shorten the prayer when visiting her family if she does not intend to stay for more than four days, because her family's country is not considered her homeland at that time. When she returns to her city of work, prayer is performed in full, even if she stays for a day or less, because she has returned to her homeland.
