Question

Can I write " we can finish it spending a dayshift "
we will produce a sample, and it will take us one dayshift's time, can I write " we can finish it spending a dayshift " or " we will spend a dayshift to finish it ".
Is " one dayshift's time " correct ?  can I use " a " instead " one " , "a dayshift's time " ?

Answer

I would say either 'We will spend a day shift to finish it.' 
Or, 'it will take a day shift to finish.'

Hope this helps :)
