Checking into a vacation retreat doesn't mean checking out of work for many employees edgy about their job status.

A recent survey of advertising and marketing executives showed that 30 per cent checked in at the office at least once a day while on vacation - up from 19 per cent three years ago and 11 per cent in 2001.

The widespread use of cellphones and BlackBerrys is making it easier for people to check in, said Creative Group executive director Megan Slabinski. She noted as well that the economy also may make people want to stay more visible, even when they're on break. Smaller work forces hit by layoffs may also make it necessary to pitch in, even while on vacation, she said.

Nearly a third more said they were getting in touch with co-workers two or three times a week - about the same as in the past. Only eight per cent of the 250 executives surveyed said they cut off office communications entirely while on break.

To help execs on vacation stay in the break mind-set, Creative Group recommended that someone specific in the office is tasked to make important decisions while you are away. Also, email out-of-office notices should be used to let clients and co-workers know you’re away. And the Group said if you feel you really need to stop yourself from being in touch, make yourself completely unavailable. Pick a vacation spot with no Internet access or cellphone reception.
