Scores of Carlsberg workers walked off the job in protest Thursday after the Danish brewer tightened laid-back rules on workplace drinking and removed beer coolers from work sites, a company spokesman said.

The warehouse and production workers in Denmark are rebelling against the company's new alcohol policy, which allows them to drink beer only during lunch hours in the canteen.

 Previously, they could help themselves to beer throughout the day, from coolers placed around the work sites.

The only restriction was "that you could not be drunk at work. It was up to each and everyone to be responsible," company spokesman Jens Bekke said.

Beyond Carslberg many other companies who are trying to entice new recruits or hold on to smart, talented employees are offering a wide range of innovative perks and programs.

For example at Google, employees can bring their dogs to work, get subsidized massages or lunch free at seven gourmet cafeterias.

Best Buy has a set your own hours program and Pantagonia encourages you to take outdoor walks on company time.
