It applies to guys getting activated into a new position. Since he bid pay only for May, do not bid just high CHs. You'll work more. You bid a 76 hour line with 13 days off or you can bid a 72 hour line with 16 days off. For 4 hours of pay, you get 3 more days off. You can then pick up trips on your days off thereby making more money.

When you get activated, they have to honor your min days off for May!
