How can you manage schedule progress during the spring season?

Actually here you manage the resources.

You can apply one or combine some of the following options:

•  If you have cost savings, you can compress the schedule by adding many resources to the tasks that was scheduled to be done during the time off.
•  In case of low risk, Execute the tasks in parallel (fast track the schedule)
• You can have someone work in the morning during the holidays and another worker takes the afternoon shift. Another option: have one employee work Monday and Tuesday and another Wednesday, Thursday and Friday. The idea behind a staggered schedule is to always have coverage, and at the same time, give employees time off during the holidays.
• You can let the team working from home during the time offs.
• You can offer a holiday pay differential to encourage the team work during holidays.
