My work is mostly emails, telephone calls and the like, and I work from home. Up until when am I allowed to continue working on Erev Shabbat according to the most lenient opinion. Thank you.
Shabbat Shalom, Shimshon
Answer:
You can continue to work until two and a half hours (zemanios) before Shabbos.
Please see here for further details, in the paragraph beginning “working on erev Shabbos.”
Best wishes.
