Last year, Richard Laermer decided to let his employees work from home on a regular basis. “We hire adults, they shouldn’t be tied to the office five days a week,” said Laermer, who owns a New York-based public relations firm. “I always assumed that you can get your work done anywhere, as long as you actually get it done.”
 Turns out, he was wrong.
 Employees took advantage of the perk, Laermer said. One was unavailable for hours at a time. Another wouldn’t communicate with co-workers all day, which Laermer found suspicious. The last straw, he said, was when someone refused to come in for a meeting because she had plans to go to the Hamptons. “That was the most unbelievably nervy thing I’d heard in years,” he said.
