Fire chiefs in Essex have been accused of undermining relationships with union members, ahead of a second fire-fighters' strike.
The one-hour strike is scheduled for 4 o'clock this morning. But any firefighters taking part have been warned they'll be forced out of bed - and off the premises - depsite the unsociable hour.
The Fire Brigade says they'll be considered trespassers if they stay in the building.
Union officials say they're protesting against a reduction in front-line firefighter numbers but the fire service says it has made a number of concessions, including promising there will be no redundancies.
Hundreds of firefighters are going on strike in Essex today.
The Fire Brigade union says members will walk out at 10 o'clock in the morning, returning at six.
The Essex Fire Service says "excellent contingency plans" are in place.
