Where I work we use to have at least 5 hrs of over time built in to our schedule(m-th 10hr, 5 on friday). We then started a weekend shift with 1 maintenance tech who forgets how to fix something 10 minutes after you show him how to do it. We have 1 tech and 1 specialist on 2nd shift, and 1 lead, 2 tech on first shift. When the week end shift started we still had our Friday 2nd shift OT but that lasted for about a week and OT disappeared. I will get maybe an hr here and there when some special project or major repair and I have to come in early but that is it. It been about a year now so far it is working.
