One thing I have learned in my years of ministry is this:
If your church gives you vacation time you use it. Use every day of vacation time. Now the work-a-holic or the youth minister who things that life in the church will not continue to flow without them there may find it hard to use the time up.
Rest is important to your health, your family, your ministry, your creativity. Make sure to take that time to rest. Don't answer work related e-mail or calls. Avoid any social networking that might draw you back into "work mode". Go "dark" if you have to.
If your church is not giving you vacation time you need to request at least 2 weeks paid vacation per year. If your church is in a financial situation where raises aren't possible it would be a nice idea for your church to offer you more vacation days or personal days as a "raise".
This week I'm resting. I'm on staycation. Of course when you live in a vacation destination staycations are pretty nice.
