Thank you!

An alternative to running three anovas (one for each year) is to do a within subject anova with a 2nd factor added. Essentially this would do a within subject ANOVA for the years and seperately (but in the same analysis sort of like a special form of two way anova) look at whether shift influenced the variable. You would also, or could also, see if these interact (that is year and shift).

If you did this you would be assuming essentially that there was some intervention occuring between each year so I don't know if that is a reasonable technqiue for your data. You might ask someone with in depth knowlede of ANOVA about that - I do simple stuff in it
