Hi, regarding the remaining two days, do they need to support from home? I presume so! You can make a simple circular.
Please refer to the following:
Dear Employees,
Due to the current ongoing project requirements, it has been decided that all employees should support from the office for 3 days a week and work from home for the remaining 2 days. Please plan accordingly. You can choose to work on Tuesday, Thursday, and Friday or on Monday, Wednesday, and Friday.
All are requested to confirm their choice of 3 working days as mentioned above.
Feel free to contact the HR Department for any questions.
Regards,
HR Team
