Give them each a stick with a nail on the end and have them patrol the national forests and parks picking up trash. That’ll keep em busy.
They can be assigned to pick up trash left on the border by illegals. That will keep them busy for a while.
I used to underwrite commercial auto insurance for large fleets. When we came across drivers with a long string of accidents and tickets, we could not legally tell the employer to fire them, but our advice was to rescind their driving privileges and give them work sweeping floors, cleaning toilets, etc.--anything to get them off the road and hopefully quit their jobs. ;D
