So, I develop for a company that does workplace-surveys. And one of our report-formats has just been translated into English. And with it a description on how to read the reports. This description contains the following sentence
When historical reporting is included, the column for this year's survey will be thinner, and the column for last year will appear behind it in grey.
Is this the correct spelling of year's in this context? I'm not a native English speaker/writer, but I do consider myself fluent, and this spelling tickled something in the back of my brain.
If it matters, the report format only displays a maximum of two years at a time (this year, and last year).
