Housekeeping staff at Marriott International hotels will be able to call for help with a personal alarm system they carry with them.

The initiative comes as the company increases its focus on staff safety. The alert devices will become a standard across Marriott’s 5,000 managed and franchised hotels in the US and Canada.

The system had been tested and modified for more than a year and its rollout is expected to continue through to 2020.

“No one should ever be fearful doing their job, least of all associates on-property who are so vital to the success of our company and our industry,” said Arne Sorenson, president and chief executive officer, Marriott International.

“The safety of everyone at our properties is always a top priority as is deterring and combatting harassment of any kind. I’m deeply proud to say our entire industry is unified around these important goals.”
