I'm reading Glenn Kessler's "Fact-checking 26 suspect claims in Trump’s address to Congress/President makes false claims about border crossings, regulations, the economy, inflation and many other issues" (free-access link).

Kessler explains his judgment of falsity like this:

This is false. Trump appears to equate teleworking with not showing up for work. But he often uses inflated numbers for how many federal workers work from home. The White House budget office reported in August that 54 percent of federal employees “worked fully on-site, as their jobs require them to be physically present during all working hours,” while just 10 percent worked only from their homes. Meanwhile the Congressional Budget Office reported in April that 22 percent of federal employees usually teleworked — compared to 25 percent of private sector employees.

There are 2 problems with this fact check.
