As staffs in our section work 24 hours in 3 shifts and can only swop in a monthly basic. So kindly advise us your course(s) 4 weeks ahead instead of 2 weeks. And try not to change / cancel the lesson in a short notice. This surely can do better arrangement for the training to our staffs.

以下譯文, 雖然與閣下原文有所不同, 但沒有太大歧 義:

In consideration of often having a time lag between the frequency of making shift schedules every month and the conducting of three shifts per day by all colleagues in our department, we suggest that the date of announcement concerning the matters of courses including confirmation, cancellation and alteration should be advanced from two weeks to four weeks, thereby enabling our department to arrange well for training our colleagues.

Because this sector is a daily three-shift staff working in shifts, and we have a month more on the preparation time, so now propose courses to your department to confirm the notice period from two weeks to four weeks ahead of publication, and as far as possible Do not change or cancel the course date. This proposal will enable the department to more effectively arranging for training.
