- I work morning SHIFTS. My friend works night SHIFTS. ---> "shift" needs to be plural. - I DO morning SHIFTS. My friend DOES night SHIFTS. ---> again, "shift" needs to plural and also "have" is used for possession, so "do/does" is better because it is used for activities. - I CHANGED shift with my friend. We talk during the shift change. ---> "change" needs to be past tense because it is already happened. Also this is a little confusing because to change shifts with someone sounds like you were supposed to do a time but he did it instead but you then go on to say you talked during the shift change. So I actually believe you meant to say "I took over from my friend's shift", which would mean that his shift finished and yours began. - We switch shifts every month. Now I work night SHIFTS and my friend DOES morning SHIFTS. ---> again, "shift" has to be plural and also you missed the the verb "does" from the second part. - My manager rotates employees’ shifts every month. ---> this one is perfect!

Correct

It seems like there are some UK/US differences. I work the morning shift. (Regularly, or talking about a specific future day. Next Tuesday I work (or l’m working) the morning shift so I’m free for dinner.) I have the morning shift (Similar to “work” but it sounds less habitual) I change shift (wrong, but not clear what you mean) Now I work the night shift and my friend works the morning shift. In the above examples “the” isn’t strictly necessary, but it would be more common and sounds better. I do morning shift. (Understandable but not natural in American English) Perhaps you could use “do” if talking about one specific shift. I really need someone else to work tonight. OK Boss, I’ll do/take/work the night shift tonight.

Thank you Cameron.

Mostly correctly. Except for: "I DO morning shift" "my friend DOES morning shift" unless you wanted to use a time marker - for example "I have morning shift tomorrow" "I change shifts with my friend" - you need two shifts to change Finally, you need to say "please advise" (verb) or "please give me advice" (noun) hope this helps
