You never were. And there was a reason for that. Maybe you are not the person to put his 150% on the line when needed. It is ok. You do not have to be. Then you get paid accordingly.

You also didnt ask what could prompt before weekend pushes. It could be money, reputation or or compliance. Certain projects are out of your control and you have to implement in weeks notice, or have a deadline imposed by laws. Some are losing revenue so each day you do not release you are bleeding money.

So please, by all means, take your weekend off, while i plan for worst cases and make it so that friday releases are "trivial and safe" to deploy. I do not have to use it, but if i do, i do not need you around, it will be mostly automated anyway.

The problem isn't the day of the week but the fact that it is the day before time off.

If you work weekends then by all means push on Friday evening. However, don't push anything the before your next vacations.
