Sentence:

Is the sentence below correct, please let me know:
(this was sent on May 7th to employees)

“Please note, Employees who have not worked on 1st May, Thursday were to work on Saturday, May 3rd.”

Best regards!

No. As the note was sent after May 3rd, the statement should be

Employees who did not work on 1st May, Thursday were (expected) to work on Saturday, May 3rd.

If the note had been sent on May 2nd, it should have been

Employees who did not work on 1st May, Thursday are (expected) to work on Saturday, May 3rd."

Thanks for the reply, Beeesneees!

Best regards!
