Question:
A person who works from 8 in the morning to 10 at night and it will look strange if he writes down that he works so many hours, may he write instead that (for example) he worked 8 to 2 on Monday and 8 to 2 on Shabbos (instead of writing all the hours that he worked on Monday, he will write that he worked those hours on Shabbos)?
Answer:
Add some hours to Tuesday, because it is a chillul H-shem to write that you worked on Shabbos Kodesh. For a Jew to work on Shabbos is definitely strange.
Best Wishes
